The currency circle has ushered in a historic day.

Not only was the network cable unplugged, but the electricity was cut off directly for you!

Sichuan clears back cryptocurrency mining

The mines were powered off collectively and all mines were closed

It is reported that due to policy reasons, China and even Sichuan, the world’s most important gathering place for Bitcoin mining machines, will usher in a large area of ​​mining machines. According to calculations, the shutdown load is about 8 million. Following Inner Mongolia and Xinjiang, Sichuan, which is dominated by clean energy and hydropower, failed to become the last bastion of Bitcoin mining in China.

A document “Notice of the Sichuan Provincial Development and Reform Commission and the Sichuan Provincial Energy Bureau on the Cleanup and Shutdown of Virtual Currency “Mining” Projects” shows that for virtual currency “mining”, relevant power companies in Sichuan need to start on June 20 The screening, clean-up and shutdown work has been completed a few days ago.

The document shows that the people’s governments of various cities (prefectures), the State Grid Sichuan Electric Power Company, the Provincial Energy Investment Group, the central power generation enterprises in Sichuan, and the provincial state-owned power generation enterprises should follow the spirit of the 73rd executive meeting of the provincial government to implement the State Council’s financial The 51st meeting of the Stability and Development Committee on the requirements of “combating Bitcoin mining”, hereby notify the relevant matters as follows: 1. Complete the screening and shutdown of key objects. The Provincial Electric Power Company has reported 26 suspected “mining” projects, and the screening, cleaning and shutdown will be completed before June 20; 2. Carry out self-examination and self-correction by power generation companies, and immediately stop supplying power to virtual currency mining projects; 3. Do a thorough investigation and investigation. The municipal (prefecture) governments will immediately carry out a dragnet investigation, and the suspected projects will be shut down immediately and completed before June 25; 4. Earnestly fulfill the main responsibility, and must complete the cleanup and shutdown tasks with quality and quantity. Due to the abundant hydropower resources, a large amount of hydropower is abandoned in Sichuan during the wet season. In this regard, the Sichuan Provincial Government Office issued the “Sichuan Province Hydropower Consumption Industry Demonstration Zone Construction Implementation Plan” in August 2019, confirming Pilot projects for hydropower consumption industry demonstration zones will be carried out in 6 cities and prefectures, including Ganzi, Panzhihua, Ya’an, Leshan, Liangshan, and Aba. In 2020, Sichuan has successively approved two batches of hydropower consumption demonstration enterprises, and the list has covered many mining enterprises in the name of big data technology. On the evening of the 19th, a small video began to circulate in the circle of friends. The content was that the miners were cutting off the power of the Bitcoin mining machine, and the rows of beating green lights went out one by one. Many people at the scene said: Bye, See you. A miner A said, “An era is over, bye bye! Although the breeze is hard to blow me, how can the moon not shine. The ice can’t stop the water, and the dead wood will be in spring again.” Miner B also issued an article saying, “At this time last year, it was just in the domestic unblocking period. The first conference in the circle was the Sichuan-Chengdu Water-rich Mining Conference. Today’s time has passed. The mining boom at that time was integrated into the bright galaxy tonight. Later, industry practitioners You should also remember the glory here.” Practitioner C said, “Sichuan’s 8 million loads will be collectively shut down at 0:00 tonight. In the history of the blockchain, the most tragic and most spectacular scene of miners is about to happen. How far-reaching the impact is here will be known in the future. ” Practitioner D: “Today, we can officially announce the end of an era.” Of course, the happiest thing is that graphics cards can finally be reduced in price. Bitcoin’s entire network’s computing power plummeted overnight According to reports, Sichuan is the largest gathering of Bitcoin miners in China and even in the world, with approximately 8 million loads being used for cryptocurrency mining. According to data from btc.com, the current average computing power of the entire Bitcoin network is 126.83 EH/s, which is nearly 36% lower than the historical high of 197.61 EH/s (May 13). At the same time, Bitcoin mining pools with Chinese backgrounds such as Huobi Pool, Binance, AntPool and Poolin have fallen sharply in their computing power. The decline in computing power in the past 24 hours has been 36.64%, 25.58%, 22.17%, and 8.05%, respectively. Many places have already shot On May 21, the Financial Stability and Development Committee of the State Council (hereinafter referred to as the Financial Committee) held its 51st meeting to study and deploy key tasks in the financial sector in the next phase. The meeting was presided over by Liu He, member of the Political Bureau of the CPC Central Committee, Vice Premier of the State Council, and Director of the Financial Committee. Relevant responsible comrades from member units of the Financial Committee attended the meeting. Two points of this meeting were impressive: The first is to crack down on Bitcoin mining and trading activities, and resolutely prevent individual risks from being transmitted to the social field. The second is to maintain the smooth operation of the stock, debt, and foreign exchange markets, severely crack down on illegal securities activities, and severely punish financial illegal and criminal activities. In late May, Inner Mongolia, Sichuan and other places successively held seminars on virtual currency mining to strengthen the crackdown on related behaviors. On May 25, the Inner Mongolia Autonomous Region Development and Reform Commission issued the “Eight Measures on Resolutely Cracking Down on and Punishing Virtual Currency “Mining” (Draft for Comment). On June 9, the Qinghai Provincial Department of Industry and Information Technology issued the “Notice on the Comprehensive Shutdown of Virtual Currency “Mining” Projects”, requesting clean-up and rectification. It is strictly forbidden to initiate and approve various virtual currency “mining” projects in various regions, and to completely shut down all existing virtual currency “mining” projects. At the same time, resolutely investigate and rectify the project entities that set up projects in the name of big data, supercomputer centers, etc. but are engaged in virtual currency “mining”. On June 12, people from the Yunnan Provincial Energy Administration Office confirmed that according to the notice, various power-using departments will be organized to carry out joint inspections in a timely manner. At the end of June this year, Bitcoin mining companies will be cleaned up and rectified, and Bitcoin mining companies relying on power generation will be seriously investigated and punished. Enterprises, unauthorized private connection of electricity, evasion of national transmission and distribution fees, funds, and additional profit-making illegal activities, once discovered, immediately suspend power supply; severely investigate and punish power generation companies who use the generated electricity to privately transfer bitcoin without permission The illegal behavior of mining companies to obtain illegitimate benefits by supplying power; seriously investigate and deal with hidden dangers in the power use of Bitcoin mining companies, and immediately order them to shut down and make corrections once they are discovered

Mining in Bolivia Lithium rush in the Andes

As of: 06/20/2021 4:40 p.m.

The largest lithium deposits on earth are believed to be under the Uyuni salt lake in Bolivia. The planned dismantling of the metal, which is important for batteries, raises hopes, but is controversial because of the high water consumption.

By Anne Herrberg, ARD Studio Buenos Aires, and Matthias Ebert, ARD studio Rio de Janeiro

It lies dazzling white between the majestic peaks of the Bolivian Andes, an area nine times the size of Berlin: the Uyuni salt lake. Hidden underneath is a treasure: white gold, lithium, or as Panfilo Huayllas, Mayor of Rio Grande says: “our future”. He demands: “All communities around the salt lake and all Bolivians must benefit from the lithium that is under this salt crust.

Lithium, the lightest metal on earth, is required for lithium-ion batteries. They are not only found in cell phones and laptops, but also in electric cars. Without lithium there is no e-mobility – and nowhere in the world are more reserves believed than here, on the roof of the Andes.

Bolivia doesn’t just want to be a supplier of raw materials

But Bolivia wants to be more than just a supplier of raw materials. “We local residents have to share in the profits, because we will feel the effects of lithium industrialization here in Rio Grande,” says Mayor Huayllas.

Lithium is said to be a driver for Bolivia’s industrialization. The plan is to build the batteries yourself. Ex-President Evo Morales was once looking for partners for this project – and found them in a German medium-sized company: ACISA from Zimmer ob Rottweil on the edge of the Black Forest. It was a deal of the century. But it burst in 2019 , after the election overshadowed by allegations of fraud and Morales’ flight into exile. Since then, the German-Bolivian project has been on hold.

Not everyone is enthusiastic about it anyway. Luis Machaca is the spokesman for a citizens’ initiative that opposes the project. “The Germans wanted to mine our raw material behind our backs, with a contract for 70 years,” he says. “They may be a good partner, but they have neither the technical means nor the technology.”

Lithium mining uses up a lot of precious water

What does mining mean for people, but also for the sensitive ecosystem? It is about the most precious commodity on the roof of the Andes: water.

A look across the border into the Atacama Desert to Chile: SQM has been mining lithium there for 25 years. The brine is pumped up from 40 meters, then evaporates in basins over months until a lithium-containing slag remains. It is a very water-intensive process, of all places in one of the driest regions in the world, says the Chilean biologist Cristina Dorador. “We can see from satellite images over the past 20 years that the soil has lost moisture,” she says. At the same time, the ground is heating up and the vegetation is receding. “These changes are directly related to lithium production over the past 20 years.”

Water protection should be improved

The company promises to make mining more sustainable. In Chile’s new constitution, on which the biologist Dorador will also be co-writing, environmental and water protection should be a top priority. Local residents like Cristian Toroca remain skeptical. “The company had not previously intended to involve local residents, that bothers us about this group,” he says. “They’re pulling this mineral out of the ground to sell in Europe as a clean product, but that’s a lie.”

In Bolivia it is still unclear who will be awarded the contract: the Germans are competing with Chinese and US companies. Panfilo Huayllas continues to hope that the white gold will bring prosperity to his community. But he too says: not at any price. “Alternative ways of supplying lithium production with water in the future must be found. If they only tap our wells, we will ruin the future of our children.”

Plan from El Salvador Bitcoin mining with volcanic energy?

Status: 10.06.2021 12:45 p.m.

Completely clean, completely renewable: El Salvador’s President Nayib Bukele plans to mine Bitcoins with the help of energy from volcanoes. This is how the country wants to get its high energy consumption under control. El Salvador wants to use geothermal energy from volcanoes for the energy-intensive mining of the crypto currency Bitcoin. President Nayib Bukele tweeted that he had commissioned the state-run geothermal electricity company LaGeo to work out a corresponding plan. The President is convinced that this is very cheap, 100 percent clean and renewable, does not generate any emissions and will develop quickly. There are more than a dozen volcanoes in El Salvador, many of which are still active.

Huge energy requirements

The immensely high energy requirement of Bitcoin mining has been discussed critically in public for a long time. The Cambridge Center for Alternative Finance (CCAF) is working on this topic and has created an index on it . The Cambridge Bitcoin Electricity Consumption Index is supposed to estimate in real time how much electricity is currently being used for mining. The data is then extrapolated to the year. The calculated value is currently around 111 terawatt hours. This corresponds roughly to the annual electricity consumption in the Netherlands. According to the Federal Environment Agency, Germany consumed around 553 terawatt hours in 2020. According to a study by Bank of America, the global Bitcoin industry emits a total of 60 million tons of CO2 annually, which corresponds to the emissions of around nine million cars.

Bitcoin as a means of payment …

A few days ago, Bukele announced that El Salvador would be the first country to introduce Bitcoin as legal tender . He expects the move to create thousands of new jobs in the Central American country. Among other things, taxes should be able to be paid in Bitcoin. Bitcoin is the most popular digital currency. It is not issued by a central bank, but created using a decentralized computer process known as mining. It is by no means clear whether it is even suitable as a means of payment.

… or as an object of speculation?

Because so far, cryptocurrencies have mainly attracted attention as speculative objects, the value of which is subject to extreme fluctuations: Bitcoin was quoted at more than $ 55,000 around May 10, and is currently around $ 36,000. If the value of part of the income is exposed to such strong fluctuations within a very short period of time, this poses a number of problems for a state budget policy. The high volatility of cryptocurrencies is also an incalculable risk for companies. The US electric car maker Tesla, for example, started in March of this year To accept Bitcoin as a means of payment for its vehicles and reversed this step a little later . As a justification, Tesla boss Elon Musk referred to the “insane” energy consumption of prospecting. But it is likely that Musk, as a businessman, at least had these price fluctuations in mind.

However, from the end of November 2020, the factory stopped working. This is like a knife cut into the despair of the nearly 300 inhabitants living on the island. These people are forced to drink contaminated water, fear outbreaks of disease and face the fear of prolonged starvation. Impotent “Skin diseases and diarrhea are widespread, especially among children. We have no choice but to drink contaminated water or salt water,” said Taboree Biremon, a resident of Banaba island. “The kids are not okay because they don’t understand (why do we have to deal with this). They keep asking for the kind of food they never get. We just feel so sad about it but what can we do?” According to Mr. Taboree, it has been 3 months since people have had no fresh water to drink, cannot bathe, have no food other than fish because all crops have died. “We couldn’t sleep either. All we wanted was to find water on the island. We are looking for a way to survive. We were adrift in the sea, lost and no one cared,” Mr. Taboree said. Empty food shelves – a familiar image in many houses in Banaba. Photo: Guardian. A ship from Kiribati – 400km away – docked this past March – providing bottled water and equipment to set up a new desalination plant. But island seniors insist relying on remote support is not feasible and sustainable, especially as the climate crisis worsens. “Dealerization plants are not a long-term solution. As the incident continued, we were in the same impasse again. What the people need is to restore the status of the island,” said Roubena Ritata, a village elder. Banaba leaders are looking for a lasting solution. In fact, there is a solution that their ancestors have worked for decades to survive on this island: the traditional method of drawing water. Reason Elders are writing to the Australian and New Zealand governments asking for assistance in building or cleaning up a network of underground water in the caves, called te bangabanga . Australia and New Zealand contributed to the destruction of the bangabanga te system in the 20th century from phosphate mining. This activity was started by Australian miner Albert Ellis in 1900. Over the next 80 years, the British Phosphate Commission (BPC) – owned by Australia, New Zealand and the UK – exploited Banaba Island so much that about 90% of the island was bare land. “The total destruction (Banaba island) is the result of the activities of these countries. They come, fill their pockets, and leave,” said Katerina Teaiwa, an associate professor at the Australian National University and author of “Ocean Island: The Story of Man and Phosphate from Banaba”. The Banaba has historically survived many severe droughts thanks to caves and water storage. The underground caves are called te bangabanga. Photo: Guardian. However, the elderly residents here claim that almost all of the caves have been destroyed, the remaining few are seriously polluted. “For many people, te bangabanga exist only in stories and dances that have been passed down through generations,” said elder Pelenise Alofa. Historically, only women have been allowed to enter these caves, showing the importance and role of women in the Banaba community. “We performed dances and told the story of how the ancestors found the cave to the young. It’s part of the people of Banaba. I thought these problems would be solved, but they got worse,” said Alofa. The Banaba used to receive a compensation for what they had to endure. In 1976, a group of people sued the UK over the destruction of the island’s nature. The court then ruled that Britain had only a moral debt, not a legal obligation. In the end, the British government decided on behalf of the group to offer the Banaba people a good faith settlement of nearly $7.8 million, on condition that they waive all further legal action. Now, as the drought persists, the Banaba people are forced to continue their search for compensation and find a lasting solution. Looking for justice 6,000 people were forced to migrate from the island to the Fijian island of Rabi. “Banaba citizens living in Fiji and the diaspora in Auckland are eager to return to Banaba and connect with their homeland. But the devastation caused by mining operations leaves people with no other choice,” said Rae Baineti, director of the Kiribati Auteroa Diaspora Director. “As a social activist, I advise the younger generation to stand firm and be brave. I encourage them to dialogue to hold the government accountable for our destruction of land,” he added. An old cantilever used to load phosphates for ships. Photo: Guardian. Over-mining has also resulted in houses in Banaba being built with asbestos. This substance when inhaled can lead to two deadly diseases, lung cancer and mesothelioma. Mike McRae-Williams, an Australian environment expert with over 30 years of experience in the mining industry, came to Banaba in 2008 to assess the severity of the situation. “This is a serious health hazard to the people who live here,” he said. “Instead of constantly giving stories like ‘poor Banaba people, no water, help them’, we should aim for an approach that is to find a reasonable solution,” said resident Teaiwa. While supporting the emergency rescue effort along with the Kiribati government, a spokesperson for the New Zealand Department of Foreign Affairs and Trade declined to comment on the Banaba residents’ request for New Zealand and Australia to address the root of the crisis. panic. Meanwhile, the Australian Department of Foreign Affairs and Trade did not provide an answer to this issue.

Specifically, leaders in Qinghai province ordered the closure of Bitcoin mining pools on Wednesday (June 9) and banned related companies from operating in the province. On the same day, leaders in the city of Changji in the Xinjiang Autonomous Region ordered the closure of the mines here, which hold the largest Bitcoin mining capacity in the world. Inside a cryptocurrency mine in Sichuan. Meanwhile, searches for the keywords Huobi, Binance and OKEx have also been blocked on the search engine Baidu and on the social network Weibo. These are the three major virtual currency exchanges in the world and are used by the Chinese to trade cryptocurrencies. This is the second time Weibo has blocked cryptocurrency-related content in the past few months. In March, the social media accounts of the three exchanges were blocked by Weibo for unknown reasons. Earlier, Weibo also blocked the account of Binance co-founder and famous shark Justin Sun. A series of moves to crack down on virtual currencies from China has caused Bitcoin to plummet since the middle of last month, at times dropping more than 50% from its peak to $30,000. The reason given is because virtual currency mining goes against China’s goal of being carbon neutral by 2060. According to data from the University of Cambridge, Bitcoin miners consume about 111.5 Terawatts per hour in a year, equivalent to the total electricity consumed in the Netherlands. On Monday, the Chinese regulator held a meeting to emphasize the task of strengthening the supervision of blockchain platforms, VPN (virtual private network) services and cross-border technologies with gambling elements. . China is taking over the world’s largest Bitcoin mining capacity. (source: Cambridge University) China currently accounts for about 65% of global Bitcoin mining capacity, according to the University of Cambridge. Among them, the regions of Xinjiang, Sichuan and Inner Mongolia currently account for the largest capacity. Qinghai province ranked ninth, accounting for about 0.26% of total capacity. The Inner Mongolia region began cracking down on miners in February and shut down 35 mining companies at the end of April. Sichuan is currently the most neutral place when it comes to hydroelectricity instead of coal mines and no new policy has yet been introduced. Outside of China, miners are actively looking for new homes. The President of El Salvador has officially recognized Bitcoin as a legal currency and promoted the mining of this virtual currency using geothermal energy from volcanoes.

At this time, the peach season begins. On the streets, traditional markets or “web markets”, peaches are sold in abundance. However, in addition to Sa Pa peaches, smooth peaches, gold hearths, crows, … new types of strange red crows appeared in the market. According to the clues, this is a Chinese peach, the outer skin is dark red, the inside is yellow, the sweet crunchy taste is no different from the Vietnamese peach. Due to its fancy look, large fruit and beautiful code, this peach is being bought by housewives to eat, even though the retail price is up to 100,000 VND/kg. Strange peaches with dark red skins flood the Vietnamese market Chinese suckling mangoes are selling well amid the high harvest of Vietnamese mangoes As noted by the reporter of Nguoi Lao Dong Newspaper, recently, the Ho Chi Minh City market “re-exported” the motorbikes peddling mangoes, also known as ripe yellow mini mangoes, quite similar to Chinese sucking mangoes, attracting quite many buyers. This mango is sold for 25,000-30,000 VND/kg. Mr. Nguyen The Bao, Director of Suoi Lon Mango Cooperative (Dong Nai), this year, Chinese mangoes ripen early, hitting the Vietnamese mango season, so competition is fierce in both domestic and export markets. Meanwhile, domestic mangoes are in full season and cheap. An Giang low-seeded mango is 9,000-15,000 VND/kg, precious quarter mango is only 15,000 VND/kg, Vip Taiwanese mango is only 7,000 VND/kg… On the “web market” instead of selling by weight as before, Mangoes are now sold in sets of several pounds or in boxes. Japanese octopus whiskers super cheap price, full of online market Octopus whiskers are firm, sweet, crunchy, and are loved by many people. The price for each kilogram of Japanese octopus antennae, officially imported, is VND 800,000 to VND 1 million. Cheap octopus whiskers are sold widely online. However, according to Dan Tri Newspaper, recently, on the online market, many small businesses sell giant octopus antennae advertised as Japanese goods at super cheap prices, from only 90,000 VND/kg. If customers buy in bulk, the price is only 80,000 VND/kg and free shipping to your home. Many people suspect this type of octopus whiskers may be made in China, not from Japan. Tiny cabbage priced at 400,000 VND/kg causes fever Cabbage is a familiar vegetable in Vietnam, with prices ranging from 10,000-40,000 VND/kg. However, according to Dan Tri Newspaper, recently, a tiny cabbage, only about the size of a plum, is being sold for 400,000 VND/kg, making housewives crazy. This type of cabbage, whose English name is Brussels Sprouts, originates from Belgium, is grown in many countries such as Australia, France and is a high-class product with many nutritional values. Goat pearls priced at half a million are still sold out Goat jasper is the testicles of a male goat. Since ancient times, jade yang goat was “praised” as a “panacea” in the bedroom. Dishes from pearl goats are increasingly popular. Ngoc Duong goat stir-fried with lemongrass and chili (Photo: Dan Tri) Ms. Vu Nhien (longtime goat meat restaurant owner in Quang Ninh) said on Dan Tri Newspaper: Currently, each set of goat pearls costs from 300,000-500,000 VND, depending on the size. Coil price increased sharply Major domestic steel brands have simultaneously announced to increase the price of CB240 coil to over 18,000 VND/kg. This is the third increase in the price of coil in May. Only in May, steel price has increased by about 10%. Since the beginning of the year, coil prices have increased 15 times, a total increase of about 40%. The sharp increase in steel prices makes it difficult for construction contractors to implement fixed unit price contracts and will incur losses. The first fruits of the season are simultaneously discounted Although the season has just started, many fruits at the beginning of the season are retailed in the market at much cheaper prices than in previous years. If at this time last year, the first crop of crocodiles was sold for 60,000-70,000 VND/kg, this year the price suddenly cooled down, only 40,000 VND/kg. The price of young crocodiles is much cheaper than last year The price of early season fabric is also cheaper than every year. For example, at the beginning of last year’s season, the price of pink lychee was 100,000 VND/kg when it arrived in Hanoi, this year it is only 50,000 VND/kg. On the online market, there are people selling cloth for only 50,000 VND / 3 kg. In Ho Chi Minh City, the price of Hanoi plums for sale is only from 40,000-50,000 VND/kg, half the price of plums at the beginning of last year’s season. Durian has just popped up and arrived in many markets in Ho Chi Minh City for about 2 weeks now, but the price is extremely cheap, about 60,000-80,000 VND/kg (food bag). Great price melons, pumpkins for cows to eat bò Due to the impact of the Covid-19 epidemic, the output of cantaloupe was affected, causing the price to plummet. Ho Chi Minh City Law Newspaper information, in some markets in Ho Chi Minh City and on mobile vehicles, melons grown in fields and greenhouses are being sold for only 20,000-40,000 VND/kg, not equal to 50% of the selling price in recent years. Pumpkin prices also dropped dramatically. According to Dan Tri Newspaper, the price of pumpkin in Dak Lak is only about 800-1,500 VND/kg, causing many farmers to suffer. In Phu Yen, hundreds of tons of pumpkins are piled up without buyers and have to be fed to the cows. Cheap Chinese ice cream flooded the market According to ANTV, at the beginning of the hot summer, domestic Chinese ice cream sticks with cheap prices of only a few thousand dong flooded the market and on social networks. Cheap, colorful and attractive, these ice cream sticks are sought after by many people without knowing the real origin and quality. In fact, all of these products are imported into Vietnam through a small quota, so there are no documents on the source of goods as well as product quality control. Therefore, many small traders in Hanoi have to open many warehouses, in order to divide the source of goods, to bypass the eyes of the functional forces. Wholesale pork prices drop sharply, retail markets drop trickle According to Ho Chi Minh City Women Newspaper, for about a week now, in Ho Chi Minh City, the price of live pigs has decreased by about 8,000-9,000 VND/kg. The price of thin pork (wholesale/jaw) of grades 1 and 2 also fell sharply by about 12,000-15,000 VND/kg, to 85,000 VND/kg grade 1 and 78,000 VND/kg grade 2, respectively. mixed with snakehead has not much decrease, only about 5,000 VND/kg. The retail price of pork in some markets is still high, some places only decrease by about 5,000-10,000 VND/kg, some places do not decrease. Specialty chili ‘regiment’ expensive price Unlike the scene where farmers in Binh Dinh, Quang Ngai, Quang Nam, … have to sell chili at a cheap price, this occasion in Muong Te (Lai Chau), the regiment’s chili specialty has the highest price. sharp. Chili regiment towering prices. Ms. Nguyen Thi Su – a regiment chili grower in Kan Ho commune (Muong Te) – said: “Last year, the price of chili fluctuated from 150,000 to 220,000 VND/kg depending on the quantity and time, but this year the chili crop failed. so the price is higher. I buy wholesale from 5kg with the price of 220,000 VND / kg, sometimes the retail price of fresh chili is up to 280,000-300,000 VND / kg, customers still compete to buy. According to Ms. Su, the reason for the regimental chili’s name is to refer to their spiciness, which means that the whole regiment only ate one of these chili peppers because it was too spicy. In addition, this type of chili also has a unique aroma that makes anyone who eats it remember forever. Old, broken computer components are sold at high prices Recently, the component market has become much more active because many people buy computers for the purpose of mining coins, Dan Tri newspaper said. Even old, broken components are also bought and sold at relatively high prices. To mine bitcoin, players need to invest in a highly configurable machine, especially, the graphics card must be very strong. The price of graphics cards has now increased by 30% compared to before. According to the business world, if virtual currencies hit the bottom as before, the price of computer components can return to the true value. Hanh Nguyen (Synthetic)

Bitcoin digital currency. (Photo: AFP/VNA) On May 28, British police said they had discovered a case stealing electricity large capacity to mine the digital currency bitcoin. Specifically, in a dismantling of a cannabis plant, the anti-narcotics police force in England suddenly discovered an organization Bitcoin “mining” using a large power source to steal from the national grid. The facility is located in an industrial area in Birmingham – the UK’s second largest city. Through inspection, the police discovered about 100 computers dedicated to “mining” bitcoin. At the time the police arrived, there was no one at the facility. The case is currently under investigation. The digital currency “mining” system consumes a large amount of electricity, so some lines specializing in “mining” cryptocurrency in the world often choose to steal electricity to reduce costs and increase profits. According to Deutsche Bank, “mining” bitcoin alone consumes the same amount of electricity as Switzerland consumes each year. On May 12, the world’s largest electric vehicle maker Tesla (USA) announced that it would stop using bitcoin in its car sales due to concerns about environmental issues. CEO (CEO) of Tesla, American billionaire Elon Musk states: “Tesla stopped using bitcoin car sales. We are concerned about the growing use of fossil fuels for bitcoin mining and trading, especially coal – the worst-emitting fuel.” Iranian President Hassan Rouhani has announced a four-month ban on all crypto-mining activities after many major cities suffered power cuts due to power shortages.

Samples collected by Japan’s Hayabusa-2 probe. Pour mining money in space According to Florian Vidal (researcher at the French Institute of International Relations) and Professor of Physics José Halloy, the acceleration of ecological transition to combat climate change has led to a sharp increase in mineral demand. to service supposedly zero-carbon technologies as well as to maintain existing or newly built infrastructure. While projects to exploit mineral resources are being replicated on Earth, many “new fronts” are also being considered, such as mining in space. Typically, in 2016, the world’s media buzzed with the daring project of exploiting mineral resources on asteroids of the US companies Planetary Resources and Deep Space Industries. When Planetary Resources entered the space industry in the early 2010s, the company’s leaders were ambitious and promised to enter a new stage in the conquest of space with mining. on asteroids. Since 2012, the company’s project has attracted many private investors such as Larry Page and Éric Schmidt – the heads of Google Corporation, and filmmaker James Cameron. Excitement and enthusiasm for the field of space mining from the US has crossed the Atlantic Ocean and spread to the Grand Duchy of Luxembourg. In addition to adapting national legislation, Luxembourg’s diplomatic service has also been mobilized to facilitate the development of an area considered by the government to be strategic. By the summer of 2016, the State of Luxembourg, through the National Corporation for Credit and Investment (SNCI), spent 12 million euros to buy a 10% stake in the American company Planetary Resources. However, two years later, this partnership was broken. When the American company ran into financial difficulties, the Luxembourg government sold their shares at a symbolic price. However, Luxembourg’s participation in the space mineral exploration project has given them an international position to connect the fields of investment and invention and invention. Continuing the policy in this area, Luxembourg later continued to participate in NASA’s Artemis project to return humans to the moon. Japan, another member of the Artemis project, is also interested in the scientific study of the composition of asteroids, which is a step towards exploring potential mineral resources in space. In December 2020, Japan’s Hayabusa-2 space probe returned to Earth after a six-year mission past the asteroid Ryugu. The goal of this science mission was to prove Ryugu could have the primordial components of the solar system, and Hayabusa-2 accomplished the engineering feat of collecting 5.4 grams of matter from Ryugu at a cost 16.4 billion yen (126 million euros). Similarly, on October 20, 2020, Osiris-Rex (a NASA space probe) also performed a 6-second landing mission on asteroid Bennu to collect dust samples (regolith). Osiris-Rex is expected to return to Earth in 2023 with the collected dust sample. The cost of this mission is about $800 million and about $183.5 million for the Atlas V rocket. Perspectives under the sea To cope with the world’s growing mineral demand, undersea mining is often seen as a solution due to the vastness of this space. Among the countries interested in undersea mining is Norway. After 3 years of seabed exploration, making the Nordic country a leader in this new mining industry, in January 2021, the Norwegian Ministry of Oil and Energy announced the possibility of issuing a license from 2023. Mining permits are available to interested businesses, such as allowing Nordic Mining ASA’s Nordic Ocean Resources AS to exploit deep seabeds rich in copper, zinc, cobalt, gold and silver ores. According to many estimates, there is 6.9 million tons of copper on the Norwegian continental shelf. Japan also has similar plans, with the ability to start exploiting the seabed from 2026. In Canada, DeepGreen (based in Vancouver) in 2019 announced to raise an investment of 150 million. USD to begin exploration for mineral resources in a part of the Pacific Ocean. This is a sign of growing confidence in the industry’s future. However, mining depends primarily on the market price of the metal and the reduction in the cost of mining in the marine environment. The consequences of fishing for marine ecosystems are also of great concern. Scientists warn against switching too quickly from exploration to exploitation because humans still have little understanding of the vast undersea environment and life on the seabed. Controversy over regulations The development of mining activities in the new “fronts” mentioned above also poses the need for appropriate regulations to adjust. This is also what the leaders of the countries have seen. Typically, the International Seabed Authority (ISA) has spent many years drafting a Code for Future Undersea Mining – an indispensable tool for monitoring possible mining activities. deployed. Regulating is considered vital to seabed mining in deep waters such as the Clarion-Clipperton Zone (CCZ) which extends from the Hawaiian Islands to the Baja California peninsula and lies on the road. fault of the Pacific Ocean. This vast area is believed to have reserves of 247 million tons of nickel and 226 million tons of copper. However, many studies have shown that hidden in these spaces is a unique biodiversity and their density is reinforced by the presence of multi-needle nodules located at a depth of 4-5 km. Currently, the debate over regulations for these activities is still raging. While the International Seabed Authority recommends a gradual adjustment of regulations on a step-by-step basis when there are actors involved in seabed mining, it is also argued that such a gradual adjustment is slow. Slow, follow reality. Some argue that it will be difficult to modify the rules of conduct once mining has started. Experts say that although the exploitation of the ocean floor does not fully compensate for the activities taking place on land, it is a necessary additional source to meet future needs. But, as with space, deep-sea mining initiatives are posing dilemmas about extracting resources in increasingly remote regions. All opinions are that, whether on land or at sea, the conservation of ecological balance is a criterion to consider mining projects.

The move comes after Chinese Vice Premier Liu He said last week in a statement that it was necessary to “suppress the behavior of Bitcoin mining and trading” to prevent “the transmission of personal risk to social spheres”. Those comments are seen as Beijing’s intention to further block Bitcoin trading and other crypto-related activities. Inner Mongolia’s latest draft proposals are aimed at telecommunications and internet companies involved in cryptocurrency mining. The Inner Mongolia Development and Reform Commission said such companies could have their business licenses revoked if they are found to be involved in Bitcoin mining. In addition, cloud computing or data centers may have their government incentives revoked. In addition, there are severe penalties for individuals involved in money laundering through cryptocurrencies. Inner Mongolia’s tough stance on crypto mining began in March after it announced plans to ban new crypto mining projects and shut down existing operations to cut consumption. energy. China’s Northern Region failed to meet Beijing’s energy use targets in 2019 and subsequently set out a plan to reduce power consumption. In the case of Bitcoin, miners purposefully use computers to solve complex mathematical puzzles that allow a Bitcoin transaction to take place efficiently. These miners are rewarded with Bitcoins. But because the computer has a large capacity, it consumes a lot of energy. According to the Cambridge Bitcoin Electricity Consumption Index, Bitcoin mining consumes around 112.57 terrawatt-hours (TWh) per year, more than the consumption of countries like the Philippines and Chile. China accounts for about 65% of the world’s Bitcoin mining. Of that, Inner Mongolia accounts for about 8% globally due to cheap energy prices, a larger share of Bitcoin mining in the United States. China’s tough stance towards cryptocurrencies is not new. China previously shut down local cryptocurrency exchanges in 2017 and that same year also banned initial coin offerings (ICOs). But Bitcoin trading continues to operate in China even though exchanges have moved overseas. Inner Mongolia’s scrutiny of Bitcoin mining activity in particular comes as China tries to continue the move. Chinese President Xi Jinping said last year that China has set a goal of becoming carbon neutral by 2060. But according to a study published in Nature Communications in April 2021, Bitcoin mining could “undermine emissions reduction efforts” going on in the country. The energy consumption of Bitcoin mining operations came back into focus in early May after Tesla CEO Elon Musk said the electric carmaker would stop accepting the digital currency for the reason due to environmental concerns. On Monday (May 24), Musk said in a tweet that he has met Bitcoin miners in North America and that they are “committed to announcing current and planned uses of renewables.”

According to the clues, this is a Chinese peach, the outer skin is dark red, the inside is yellow, the sweet crunchy taste is no different from the Vietnamese peach. Due to the strange look, large fruit, and beautiful code, this peach is being bought by housewives to eat. In many places, goods cannot be sold in time, even in a state of being sold out because of overload. Hoai Phuong – a wholesaler specializing in this product in Lao Cai – confirmed that the red peaches that are causing a fever, which are being sold widely recently, are peaches in Mong Tu (China). Yesterday’s shipment was about 1 ton, she was sold out. Strange peaches with dark red skin are flooding the Vietnamese market this time Every year, Ms. Phuong often sells Chinese smooth peaches, fairy peaches and blue-shelled crow beaks, while she is selling the deep red crow beak – also known as red feathered peaches – this year. Compared with other types of peaches of Vietnam and China, the price of this type of peach is 2-3 times higher. “I poured wholesale from a box for 360,000-380,000 VND/barrel (7kg), calculated to cost 51,000-54,000 VND/kg, of which the small type is 4-5 fruits/kg, the large type is 3 fruits/kg.” . She said and said, at the beginning of the season, the fruit is beautiful, crispy and sweet, not pale, sour or soft like at the end of the season, so the goods are as expensive as fresh shrimp, wholesale customers are ordering a lot. Ms. Nguyen Thi Ngan – a focal point selling fruit in Vinh Phuc, admitted that the strange peaches with dark red skins being sold on the market today are Chinese domestic peaches. This peach is sweeter and more fragrant than other peaches, so this time I sell very attractively, up to a few quintals per day, many days sell a ton, even the goods do not arrive in time to sell,” she advertised. Not only selling to wholesalers in the province and surrounding areas, she also specializes in wholesale to Hanoi for 370,000-390,000 VND/barrel (7-9kg). Customers taking more quantity will get a discount price. For example, if you get from 5 crates of crow mining, it will cost 350,000 VND/barrel (7kg), taken from 10 boxes will cost 335,000 VND/barrel. This peach has a dark red skin on the outside, and the inside will turn from white to yellow when ripe In the market, this red peach is very expensive Customers buy less, then a few boxes, buy up to dozens of boxes. Many customers who did not book early had to wait for the goods to return to the next trip, Ngan said. As a focal point specializing in selling fruit online in Ton Duc Thang (Dong Da, Hanoi), Ms. Nguyen Huyen Trang admits that, although she has only sold this type of crow mine for a week, due to its beautiful and fancy design, many women I am curious to buy and try. Every day she returns about 60-70kg, many days only selling until about half an hour is sold out, because the goods are only enough to order for customers who have pre-ordered, rarely have a surplus. According to her, this is a “hot” product of this year’s peach season, so the price is quite expensive, up to 3 times more expensive than peaches sold in the market. Although the retail price is up to 100,000 VND/kg, customers order a lot. Most people buy 2-3kg at a time to eat, make peach tea or bring as gifts. Ms. Trang also confirmed that this is a peach of Chinese origin, not a Sapa peach or a red Ha Giang peach. However, this is a guaranteed domestic product, not a floating market, so many women trust to buy it on this occasion, she added.

His arguments include Phoenician mining activities along rivers, Biblical names in mining-related areas, to passages in the Hebrew Scriptures that seem to be related. to King Solomon and the seafaring Phoenicians, a potential Spanish city famous for its rich mineral wealth in the Hebrew Bible. King Salomon, a rich king according to the Hebrew Scriptures. If this claim is true, it means King Solomon was an ancient shipping tycoon. The Hebrew Bible says that King Salomon was extremely rich and undertook many construction projects and his role in transportation could explain his wealth. Arguments for the Solomon’s mining expeditions The Phoenicians flourished throughout the Mediterranean world from about 1,500 BC to 300 BC. According to present-day Lebanon, they sailed across the Mediterranean, establishing settlements and trading networks as far back as Portugal. Kingsley started his research about 10 years ago. It seemed that King Salomon had been wise in his maritime plans, he noticed. He recorded the trips from Jerusalem and the Phoenician sailors took all risks at sea. Archaeological excavations over the past century have unearthed remains of Phenicia mining operations near the Rio Tinto River in southwest Spain, he said. Some places today along the river of Spain have biblical names – such as “Solomon’s Hill”, says Kingsley. Furthermore, he claims, silver artifacts found in Israel contain lead isotope patterns suggesting that silver came from Spain. However, researchers have done the analysis that silver from Spain did not come to Israel during King Solomon’s time, but after he ruled. Then there is a Hebrew Bible, which describes how David and his son Solomon took raw materials for construction projects from a man named Hiram, the king of a Phenicia city named Tire in present-day Lebanon. . Kingsley hypothesized that Hiram would send mining expeditions to Spain with the financial assistance of Solomon. Passages in the Hebrew Bible also mention a place called Tarshish, where the Bible says there are many minerals. This is also the place where Johna tried to run away when God told him to come to Nineveh, according to the Hebrew Bible. Tarshish claimed that Tarshish was located in what is now Spain and Solomon financed Phenicia’s travels to the area. Kingsley argued that passages in the Hebrew Bible discuss how Hiram provided materials for David and Solomon for their construction projects, giving the idea that Solomon had sponsored Phoenician journeys. . Confirming Tarshish’s place in the Bible, Kingsley notes that a Phoenician inscription, dating back to the ninth century BC and found in Sardinia, refers to a Phenicia military force fleeing to Tarshish. after a failure. Ancient Greek records also mention a city called Tartessos – sounding similar to Tarshish – thrived in southern Spain, Kingsley wrote in an article in Spain. From historical research, Kingsley said he could say that biblical landmarks (like the Solomon Hills) were in use since at least the 17th century and possibly much earlier. Skeptic scholars Some archaeologists and historians believe they were skeptical of Kingsley’s claims. While no one doubts that the Phoenicians were present in Spain, scholars note that there is no direct evidence regarding King Solomon to the region. “It’s still not clear that there is a Solomon kingdom,” said Steven Weitzman, director of the Herbert D. Katz Center for Advanced Morphological Studies at the University of Pennsylvania. “I don’t know any evidence of an Israeli presence in Spain at this time,” Weitzman said. There are Phoenician settlements in Spain as early as around 1100 [trước Công nguyên] and certainly for many centuries to come, but it would be too much to argue that the source of Salomon’s wealth came from there. ” In fact, the Bible says that King Salomon sent ships to the East, not to the West. Solomon’s ships were dispatched from a place called Ezion-Geber, a port town on the Red Sea, and they returned from a place called Ophir, filled with gold and other treasures. Wherever the Ophir was located, the ships Weitzman explained would go in the opposite direction from Spain, east not west. Archaeologists also rejected Kingsley’s arguments regarding silver artifacts found in Israel and Spain. “Based on all available scientific data, silver in the Solomon era,” said Ayelet Gilboa, professor of archeology at the University of Haifa, Israel. [thế kỷ 10 trước Công nguyên] not coming east from Iberia ”. Only after that, after King Salomon ruled, did silver from Spain begin to reach Israel. Gilboa worked with Tzilla Eshel, a researcher specializing in antique silver analysis at the University of Haifa, to determine the origin of ancient silver in Israel, and they published an article on this topic in 2019. that silver came from Sardinia to Israel in the 10th century BC but it was not until the ninth century BC that silver came from Spain.

Squeezing on top of a decommissioned volcano in northern Nevada, workers are preparing to blast and dig holes to mine the first large-scale lithium mine in the United States in more than a decade. According to the New York Times, Lithium is an essential ingredient in the manufacture of electric car batteries and renewable energy. This lithium mine was built on federal rental land and promises to address current US dependence on international lithium supplies. However, this Lithium Americas project was strongly opposed by members of the Native American tribe, the owner of the farm and the environmental groups. The project plans to use billions of gallons of groundwater in the area. In addition, the lithium mine has the potential to pollute for up to 300 years and leave severe consequences and huge waste of waste. The conflict surrounding the Nevada mine represents a new tense problem: Electric cars and renewables may not be as green as they seem. “Blowing a mountain is not environmentally friendly, no matter how much economic expectations people put on it,” said Max Wilbert, who lives at the proposed mine. Demand soared In addition to Nevada, private businesses are proposing other lithium mining sites in California, Oregon, Tennessee, Arkansas and North Carolina. According to the Bloomberg In the first three months of 2021 alone, lithium miners in the US raised nearly $ 3.5 billion from Wall Street, seven times the amount raised in the previous 36 months. This shows that a lithium boom is exploding as the electric car industry is becoming a new trend. Lithium is used in electric car batteries because it is light, stores a lot of energy and can be recharged many times. Analysts estimate demand for lithium will increase tenfold as Tesla, Volkswagen, General Motors and other automakers launch a series of new electric cars. Blasting a mountain is not environmentally friendly, no matter how much economic expectations people place on it. Max Wilbert, a resident of the Lithium Americans mining area. Therefore, the US needs to quickly find sources of lithium when electric car manufacturers accelerate production. Although the United States has the largest lithium reserves in the world, the country has only one large-scale lithium mine, the Silver Peak mine in Nevada. Mining started in the 1960s and produces only 5,000 tons / year – less than 2% of the world’s annual supply. Most of the raw lithium used in the United States comes from Latin America or Australia, which is then processed and manufactured into batteries in China and other Asian countries. The Lithium Americas mine under construction in Nevada is estimated to have a lithium value worth $ 3.9 billion. The operator is expected to start mining operations next year. The largest shareholder of the mine is Chinese company Ganfeng Lithium. However, traditional mining is one of the most “dirty” businesses today. For electric car manufacturers and renewable energy companies, this situation has not improved much. “While its intentions are good, the need for clean energy can do harm,” said Aimee Boulanger, executive director at mining services for BMW and Ford Motor. bigger”. “Dirty” industry On a hillside, Edward Bartell and the ranchers often go out early in the morning to make sure that 500 cows roam the 50,000-acre (202 km2) desert with enough food. Faced with a lithium mining project in the area, his family has never faced such a great threat. Not far from Bartell’s farm, the largest lithium Americans project in the United States is on the horizon. Mining ore will have helipads, chemical treatment plants and waste yards with the depth of the mine up to 112 m. Traditional mines are potentially dangerous to the environment, animals and people living in the area. Photo: NYT. Producing raw materials such as lithium, cobalt and nickel often harm the soil, water resources, wildlife and people in the area. Like the competition for gold and oil in the past, governments are taking advantage of minerals to gain future economic and technological dominance. However, in the economic and technological race between great powers, environmental issues are often forgotten. What Barbell was most worried about was that the mine would consume all the water of the cattle. The mining company said the mine would consume 3,224 gallons of water per minute (equivalent to 12,204 liters / min). Thus, the groundwater level in the land where Mr. Bartell is breeding could decrease by about 3.5m. In addition, if the mine targets to produce 66,000 tons of lithium carbonate per year, this mine could cause groundwater to be contaminated with antimony metals and arsenic. Lithium is extracted by mixing clay dug from a mountain slope with 5,800 tons of sulfuric acid per day. The documents show that the entire process produces 354 million cubic meters of waste extracted from sulfuric acid treatment and can contain radioactive uranium. A December assessment by the Ministry of the Interior found that over its 41-year lifespan, the lithium mine would damage nearly 20 square kilometers of antelope and wildfowl habitat. In addition, the mine will destroy the nesting area of ​​a breed of golden eagle and other wildlife. “It was disappointing that the lithium mine was introduced as an environmentally friendly project, when in fact it was just a giant industrial park,” said Mr. Bartell. He filed a lawsuit demanding to stop mining activities. “The war is not fair” So far, the Joe Biden administration has not moved to promote more eco-friendly strategies such as extracting lithium from sea salt water instead of opencast mining. People of ethnic minorities protest outside the land management office to protest against the Lithium Americans mining project. Photo: NYT. Mining companies, meanwhile, want to speed up domestic lithium production and push the government to include a $ 10 billion funding program in the infrastructure bill. “If China severs relations with us, the US will face many difficulties,” said Ben Steinberg, an official in the Obama administration, threatened. This war is inherently unfair. After all, the mining units are just capitalists. Maxine Redstar, the leader of Fort McDermitt Paiute and the Shoshone tribe. At the Fort McDermitt Indian Reserve, controversy over the project was even more acute and led to more conflicts. The Lithium Americas mine proposes to hire tribal members as workers with an average salary of $ 62,675 / year. This salary is double the per capita income in the region, but indigenous Indians will pay a huge price for the environment and nature. “After you pollute the water here, what will we drink in the next 300 years? You’re lying!” Said Deland Hinkey, a member of the indignant tribe. Mr. Tim Crowley, vice president of Lithium Americas, pledged that the company will operate responsibly with the local environment, planning to use steam from burning molten sulfur to generate electricity, for example. However, people here still do not trust and fear that mining activities will cause serious environmental consequences. “This war is inherently unfair. After all, the mining units are just big capitalist corporations,” said Maxine Redstar, leader of Fort McDermitt Paiute and the Shoshone tribe.

Using this algorithm, Chia mining does not consume too much power because only the hard drive is free. Chia’s network has now mobilized more than 2,700 PiB (1 PiB = 1125.9 TB) of available hard drive space. Very quickly, Chia caught the attention of Amazon and launched a virtual money mining service in the cloud exclusively for the China region. The Amazon website also shows how to set up a cloud service to create a Split wallet, create a space, and how to mine in just 5 minutes. Dong Chia is being traded on a number of small exchanges with a large fluctuation range. Dong Chia started the validation process and allowed mining on March 19, a process known as the mainnet. At that time, Chinese miners flocked to e-commerce sites to buy hard drives and sold these items out of stock, mainly in the super-hard drive segment of 10 TB or more. And after about two months, Chia was officially listed on May 4 last with the virtual currency code XCH, starting price 1,700 USD. But immediately this currency must witness selling momentum causing it to drop in value to only $ 700 before recovering around $ 900 mark. Over time, with the Bitcoin fever, new virtual currencies are constantly appearing and being pumped, making it worth fluctuating up and down. The volatility of the virtual currency market is part of the reason that many countries are afraid of Bitcoin in general and virtual currencies in particular. Phuong Nguyen (According to CoinDesk)

The stone is mined from the quarry of the company, after grinding, grinding into stone 1-2. Preeminent magnetism of new building materials Being put into trial production since May 2018, up to now, the sand crushed source from stone has been promoting its superiority as well as attraction to the construction market. Mr. Mai The Tinh – Director of Phu Son Trading Company Limited (Nga Son District, Thanh Hoa Province) said: “With abundant raw materials from the limestone quarries in the province in particular, and grinding technology modern treatment of impurities before putting finished products on the market; The durability of buildings is also appreciated higher than natural sand, which is the advantages that this new building material shows. As an enterprise located in Nga Son district (Thanh Hoa), for a long time, the supply of natural sand for its construction works as well as the district market has faced many difficulties when the sand reserve in the host area. The weak point is that the salty sand can only be leveled, so it is largely limited in the construction works, to meet the demand, the construction sand has to be imported from other districts such as: Thieu Hoa, Ha Trung, Vinh Loc … Large transportation costs leading to higher costs make investment in construction face many difficulties. Mr. Tinh added: At the end of 2017, after field testing from some southern markets as well as abroad, the Company applied and invented a new investment in a production line of crushed sand from rock at a cost. only equal to 20% (about 20 billion VND) compared with the lines imported from abroad. Crushed sand products will contribute to help businesses create a closed production process. The stone is mined from the quarry of the Company after grinding, grinding finished products (stone 1-2), will be screened, classified and put into the system of crushers, small screening into sand. The next step, crushed sand will be put into the system of sedimentation tanks, wash and treat impurities before the finished product is sold to the market. In order to ensure the environment, during the production and grinding process, there is a dust misting system. The process of putting into sedimentation tanks, washing, stone dust will also be deposited and reused as bricks … Thus, the production of crushed sand will be very suitable for quarry mining enterprises, increasing the first choice. private businesses. Mr. Mai Van Nguyen – Production executive officer of Phu Son Trading Co., Ltd. said: With an output of 500m3 / day, the unit is providing for all projects and works on construction in Nga Son district. . In addition to the superiority of the product, with the automated process, only 2 workers to operate the line are contributing to reduce labor costs, reduce human labor, and lower product costs. Meanwhile, according to enterprises in Nga Son district, materials from crushed sand are the number one choice among many large construction projects as well as small construction needs. among the people. In addition to the durability of the project, sand crushed materials also help businesses, people reduce the cost of transfer, cost … Opportunities open for businesses Mr. Luu Van Hai – Head of Economic – Infrastructure Division of Nga Son district said: With the characteristics of the district bordering the sea, the sand reserve is mostly salty, the introduction of crushed sand in the area is contributing to solving the problems. difficulties for businesses in construction investment. In addition, the Provincial People’s Committee also encourages the use of crushed sand in construction works, so this source of construction materials is currently popular and popular. “One of the typical projects using crushed sand such as: The project to solidify the Hung Long canal, through the area of ​​Nga Son town, Thanh Hoa has been put into use and the durability has been proven over time”, Mr. Hai cited. Conduct sorting and put into the system of crushers, small screening into sand. However, in addition to the superiority in production as well as the durability of the buildings, the development of this building material source still faces some difficulties. Specifically, according to Mr. Hai, this new material source has not been disseminated, the number of units investing in the production line is not much, leading to the competition on product prices is not high. If it is soon popularized for construction investment and more widely, this new source of construction materials will be a gradually replacing material source for natural sand and gravel. Learning from enterprises, Mr. Nguyen Trong Cuong – Deputy Director of Nien Cuong Co., Ltd. (Nghi Son town, Thanh Hoa) exchanged: Currently, the source of crushed sand material has been one or two units in the area. production investment town. On the business side, crushed sand contributes to increasing investment choices, making use of raw materials in the mining process … However, Mr. Cuong cannot help but wonder when this product has not yet been popularized. , product cost is higher than natural sand, leading to difficulties and barriers in the selection of projects and works. According to research, the province has 2 grinding sand production lines with a capacity of 150 tons / hour of Phu Son Trading Co., Ltd. (Nga Son district) and Ha Lien Construction and Trade Co., Ltd. (Nong district). Drain). There are also a number of small production lines such as Nghi Son town … According to the construction material development plan to 2025, with a vision to 2035 of the province, crushed sand from stone will be developed in many areas. The mine sector is available with raw materials to supply the market, with a total expected capacity of 1.9 million m3 / year. This is considered an open opportunity for businesses in the province to invest and develop.

In order to ensure the efficiency in the exploitation, processing and use of mineral resources, at the same time minimize the negative impacts of mineral mining and processing activities on the environment, dated December 4, 2008 , The Prime Minister issued Decision No. 159/2008 / QD-TTg approving the project “Innovating and modernizing technology in the mining industry to 2015, with a vision to 2025”, then, On February 22, 2017, the Prime Minister continued to issue Decision No. 259 / QD-TTg approving the project “Innovation and modernization of technology in the mining industry until 2025” (the Scheme). . The pigment factory has a capacity of 80,000 tons / year, designed by Vimluki and built in Binh Thuan province Founded in 1967 on the basis of separating from the Institute of General Design, currently the Institute of Mining Science and Technology (Vimluki) under the Ministry of Industry and Trade is one of the units researching, implementing science and technology and processing activities. Vietnam’s leading minerals in the mineral sector in general and metal minerals in particular. As soon as the project was implemented, under the close direction of the Department of Science and Technology (Ministry of Industry and Trade), the Institute has actively developed and proposed science and technology tasks to participate and always adhere to the criteria of the Project.

Research results obtained from science and technology tasks have largely transformed into promoting the process of technological innovation and modernization in the mineral mining and processing industry. Binh Dinh titanium slag factory, Vimluki consulted on technology renovation and renovation Only in recent years, Vimluki has carried out hundreds of research projects to innovate technology, equipment, consult and develop mineral exploitation and processing projects; Science and technology consultancy works on setting up and developing new projects, improving equipment, transferring and training technologies for operating factories to improve economic efficiency for mineral mining and processing activities. of businesses, reducing resource losses and limiting waste sources, causing the risk of negative impacts on the environment. Growing with Industry and Trade With the rapid growth in both force and substance, in the past 55 years, Vimluki has participated in many large mineral mining and processing projects in Vietnam, contributing significantly to the innovation and modernization of technology. the mining industry in particular and the Industry and Trade sector in general. Specifically, the Institute has implemented technology design, design and construction of Quy Xa Iron Ore Mining Plant (Lao Cai) of Viet Trung Minerals and Metallurgy Co., Ltd. with a capacity of 1 million tons / year, stable production. plan to reach 100% of design capacity since 2014. At the same time, the Institute has consulted the company to use the tooth shaft beaters of MMD, UK, to solve the problem of congestion when using the Another type of crusher produced by Quy Xa iron ore is a limonite with a high natural moisture content. Next is the Sin Quyen copper ore flotation plant project No. 2 with the largest capacity of 1.4 million tons / year in Vietnam, this project performs the role of the general contractor for the design and construction of the plant, providing equipment. and technology transfer to the final product, the factory has been operating stably, reaching 100% of design capacity with technology targets reaching and exceeding the contract signed at the end of 2018, signed by the investor. Evaluation is one of the exemplary projects in terms of progress and quality. The Quy Xa – Lao Cai iron ore sorting plant Also in the project of the Rang Dong Group’s 36,000 tons / year super-fine mill mill project in Binh Thuan, built by the Design Institute, put into commercial production from 2019, the factory’s products are now. customers from Japan, UK, EU … appreciated and sold the products. From the above success, Rang Dong Group continues to assign the Institute to implement a project to design and build a pigment production complex (TiO2) with a capacity of 80,000 tons / year from titanium ores, this is a deep processing complex of ore. titanium in the first industrial scale in Vietnam, invested by Vietnamese enterprises and domestic science and technology staff in charge of construction design, factories using advanced European technology and equipment. ensure to produce high quality, stable products and minimize negative impacts on the environment. At the same time, the Institute also directly applied research results to produce a number of metal and alloy products to serve domestic demand and export such as iron and copper alloy products. aluminum for machine manufacturing industry and machine details, tin products (Sn) 99.99% Sn … The science and technology activities of the institutes in general, the Institute of Science and Technology of Mining – Metallurgy in particular in the framework of the project have gradually changed the perceptions of managers and enterprises in the industry. In the coming years, with the set objectives, the Project will continue to carry out science and technology activities towards further promoting the process of technology innovation and modernization in Vietnam’s mining industry. direction exploit and process minerals efficiently, make the fullest use of useful minerals in mines, economically exploit resources, research into synthetic use from beneficial minerals to wastes generated in the mining process. exploiting and processing to orient mining activities according to the circular economy model, in line with the policies of the Party and the Government.

China Times (www.chinatimes.net.cn) reporter Feng Yingzi reports from Beijing

Today, “carbon neutrality” is undoubtedly one of the hottest topics being discussed. At present, more than 120 countries and two-thirds of the economies in the world have joined the “carbon neutral” transformation. Under this trend, the high energy consumption problem of virtual currency mining has also become the focus of heated discussion in the industry.

Previously, on February 25, the Inner Mongolia Development and Reform Commission announced on its official website that in accordance with the dual energy consumption control work arrangement, it will speed up the elimination of backward and excess production capacity, emphasizing: “Comprehensively clean up and shut down virtual currency mining projects, and all exit before the end of April 2021. ”

In this regard, Zhang Lu, the CEO of Hash Power 360, said in an interview with our reporter that carbon neutrality may force mine owners to accelerate the elimination of unclean energy such as coal combustion and turn to idle clean energy such as wind power and hydropower. At the same time, the cost of mining may increase, and the elimination of small computing power mining machines will accelerate.

How long can thermal power mining last?

At present, domestic mines are mainly distributed in Xinjiang, Yunnan and Sichuan. Among them, Xinjiang is dominated by thermal power generation. Yunnan and Sichuan are dominated by hydropower. Data shows that the carbon emissions of hydropower per unit of electricity are only 1/5 of that of thermal power.

However, hydropower is divided into dry and wet periods, and the electricity price in dry periods is twice as expensive as in wet periods. Judging from the data from May to October each year during the high water period, Sichuan’s mining power consumption accounts for half of the country’s mining power consumption, but in the dry season, Xinjiang accounts for more than half of the country’s mining power consumption.

Under the trend of carbon neutrality, as to the conjecture that “virtual currency mining in thermal power areas may withdraw completely in the future”, Zhang Lu said that at present, we have no way to give a particularly clear conclusion and the impact on the industry. There is no real game in the industry yet. For example, in Sichuan, the park’s electricity consumption was proposed very early but it has not been implemented because the direct power supply and the park’s electricity consumption itself have a game.

“We need to consider the value of virtual currency mining on the first day of business and how to operate in compliance.” Zhang Lu mentioned that if the electricity itself is not illegal and the filing is complete, we will first choose two places in China: No. One is Sichuan. Because of the energy support provided by the park, its companies can consume electricity that cannot be delivered to create value for the country. The second is Xinjiang Zhundong Economic and Technological Development Zone.

“In fact, in the Zhundong area, we use coal from the surface, which is a huge waste of energy if these resources cannot be used.” Zhang Lu said.

According to statistics, in 2019, the global waste of electricity reached 5.49 billion kwh, and the waste of water was about 69.1 billion kwh. The use of waste energy is what crypto mining is doing.

In addition, Zhang Lu said: “We can always choose to mine in Sichuan using hydropower. This will not cause fatal effects. It’s just that electricity bills are more expensive during wet periods. Small computing power machines are eliminated, but large computing power machines can still operate. , When the computing power of the entire network decreases, the number of bitcoins mined increases, and the impact is not significant.”

Hu Yiying, assistant to the general manager of Hash Power 360, also mentioned: “The trend of carbon neutrality will lead everyone to think longer and move to a place rich in hydropower, which is undoubtedly Sichuan.”

In the next year, the transfer of computing power may accelerate overseas

Since the beginning of this year, many U.S. stock companies have announced their entry into the computing power market. According to the latest report of Guosheng Securities, as of February 2021, about 17 listed companies have disclosed that they have purchased Bitcoin mining machines. The disclosed mining machines have a computing power close to 21E, which is 16% higher than the Bitcoin network computing power during the same period.

China is the country with the largest share of bitcoin computing power in the world, but data shows that China’s bitcoin computing power has been slowly declining since September 2019. Bitcoin computing power is quietly but rapidly moving overseas, especially in North America.

When sharing, Hu Yiying said that in March this year, China’s share of global computing power fell below 70% for the first time, dropping to 65.7%. It recovered to 71.70% in April. In contrast, the growth rate of the United States is very obvious, and its global computing power accounts for 7.24%.

The distribution and ranking of the world’s top ten major mining power regions are relatively solidified. The top three are China, the United States, and Russia, followed by countries such as Iran, Malaysia, and Kazakhstan. Relatively speaking, the next is more competition between China and the United States. The characteristics of the mining ecology of these two countries are very obvious: China’s industrial chain is very complete, because China is the country with the longest mining history. The advantage of the United States is compliance, and Wall Street has long-term fixed investment funds to enter the market.

Zhang Lu also believes that one of the important reasons for the transfer of computing power overseas is that there are very compliant deposit channels overseas. This allows them to purchase mining equipment with low-cost legal currency. In the United States, the interest rate for legal currency mining is 3%-4% per annum; in Japan, the value is 1%-2%. In China, traditional miners need to sell coins in exchange for computing power equipment, risking the skyrocketing Bitcoin to buy mining machines. In the current market environment, the “opportunity cost” of domestic mining is very high.

In an interview with reporters, Zhang Lu said that the current supply-demand relationship of mining machines is extremely imbalanced, and the supply is still stuck in the previous era, but now the demand has entered the next era, resulting in a large amount of overseas funds, especially Wall Street funds. , Rush to buy mining machines.

Overseas giants believe that the competition in the Chinese market is too fierce and there are many immature places. In the future, more and more institutions will choose to establish mines overseas. Zhang Lu mentioned that under these various factors, the computing power of overseas mines will continue to increase. She predicts: “There will be huge changes from the end of this year to the beginning of next year.”

Report

Foreign media exposed the core photos of RTX 3080Ti, It shows that its core number is GA102-225, which is consistent with previous rumors. The graphics card will be equipped with 1024 stream processors, 384-bit wide 12GB GDDR6X video memory, and the capacity is half of the RTX 3090.

CPU-Z screenshot shows, The core frequency of RTX 3080Ti is between 1365MHz and 1665MHz, which is lower than 3090/3080, which can better widen the gap in performance. However, the memory frequency of RTX 3080Ti can be overclocked from 19GHz to 21.4GHz. When the power reaches 278W, its mining power reaches 118.9MHz/s.

The mining power of RTX 3080 is about 90MHz. I didn’t expect the RTX 3080Ti to be so fierce and the increase in computing power is so large. It seems that the miners have to act again. However, NVIDIA has stated that it will limit the mining capabilities of RTX30 series graphics cards, and 3080Ti will also be restricted under normal circumstances.

RTX 3060 is limited to 50% of the computing power. If the same ratio is used, the limited computing power of 3080Ti is about 50~60MHz/s. Combined with its price and power consumption, the price/performance ratio for mining may not be so high, but as long as it is a graphics card with strong computing power, it is estimated that miners will not let it go.

In March, NVIDIA launched the first professional mining card CMP 30HX, which uses the previous generation GPU core and cancels the video output interface. The power is 125W, the mining power is 26MH/s, and the price is close to 4700 yuan. Compared with RTX 3060, there is still a gap, but it is still purchased in large quantities by miners, which brings huge revenue growth to NVIDIA.

There will be CMP 40HX, 50HX and 90HX and other mining cards to be listed in the future. The corresponding mining power is 36MHz/s, 45MHz/s and 86MHz/s respectively. It is estimated that the price is certainly not cheap. In contrast, RTX 3080Ti is still the sweet pastry in the eyes of miners.

Fortunately, the price of virtual currency has fallen in recent days. It is expected that the demand for graphics cards from miners will ease a little in the future. At that time, there may be a chance to buy graphics cards at the original price. I look forward to this day.

At the meeting, Mr. Nguyen Huu Trung – Deputy Director of Binh Thuan Department of Transport said: Over the past time, the province has stepped up the implementation of site clearance work as well as issues related to the project, especially especially the work of solving the demand for construction materials of the expressway project. Up to now, the number of households and organizations has handed over 2,657 / 2,684 dossiers, reaching the rate of 99%; The compensated clean land area was 1,204.89 ha, reaching the rate of 98.6%. 27 households have not received compensation money and handed over the premises. In addition, at the locations where the ground has been handed over, there are 25 cases (received money and signed the handover) but have not moved or handed over the site to construction contractors. Currently, the province is actively directing the People’s Committees of relevant localities to completely settle the compensation and site clearance work in May 2021.

The Economic Committee of the National Assembly’s supervisory delegation works with Binh Thuan province.

According to the report of Project Management Unit (PMU) 7 and PMU Thang Long, the total demand for construction materials for the project of the Vinh Hao – Phan Thiet section and the Phan Thiet – Dau Giay section is nearly 16 million blocks.

Deputy Director of Binh Thuan Department of Transport added: For the demand for construction sand and stone, the construction material mines in the province can meet the needs of the project. As for embankment materials, according to the approved technical design documents of the approved Vinh Hao – Phan Thiet and Phan Thiet – Dau Giay sections, the reserves of the mines in the province meet the quality and demand of the project. project. However, through the field survey at the mines, the volume of soil and soil cover mentioned above is preliminarily classified into 3 categories by PMU 7, PMU Thang Long, including: Soil, rock mixed with weathered rock and rock.

According to the assessment of the two boards mentioned above, the soil mixed with rock and weathered rock does not meet the requirements for making backfill materials according to the project’s technical requirements. Based on the proposals of the Thang Long Project Management Board and PMU 7, the Provincial Working Group is now speeding up the determination of the mines being exploited that need to increase capacity, expand the scale, or push To speed up the mining licensing procedures to guide the Miners in order procedures, shorten the time but ensure compliance with the provisions of law. At the same time, invite the Miners to work to guide the procedures for capacity increase, scaling up and mining licensing. Expected to complete the mining licensing procedures in the second quarter of 2021.

Mr. Vu Hong Thanh – Member of the Party Central Committee – Chairman of the Economic Committee of the National Assembly spoke at the meeting.

At the meeting, Chairman of Binh Thuan Provincial People’s Committee – Le Tuan Phong said: The province has drastically participated in solving the needs of building materials for the expressway project, step by step solving problems, Gradually came to agreement on issues related to the provision of soil filling materials for the project. In particular, the province has instructed the Department of Natural Resources and Environment and related departments and sectors to give priority to processing investment, environmental, land, and mining permits within 3 working days upon receipt. are business records.

To ensure the demand for building materials for the project, the Chairman of the Provincial People’s Committee suggested that the Project Management Units: Thang Long, 7, 85 coordinate closely with relevant departments and branches of the province and mine owners. to survey, evaluate and determine the reserves and quality of each field of embankment materials to unify data, propose ground-filling requirements for each specific construction and installation package, in which clearly identify which mines Exploiting operations need to increase capacity, expand the scale, which mines need to speed up the mining licensing procedures.

The Chairman of the Provincial People’s Committee also requested the Ministry of Natural Resources and Environment to guide the province to shorten the time for implementing mining licensing procedures. At the same time, it is recommended that the Ministry of Transport soon consider and approve the plan to use 1.1 million cubic meters of salvaged rock in package No. 01, Vinh Hao – Phan Thiet section to crush into expressway embankment as proposed. proposal of PMU 7; Consider and approve for the use of rock and wind mixed in mines.

The Chairman of the Economic Committee of the National Assembly – Vu Hong Thanh highly appreciated the efforts of Binh Thuan province in implementing and implementing the North-South Expressway project in the East, the section passing through the province, especially the coordination. solving the need for building materials to implement the project. Mr. Vu Hong Thanh also suggested that the province continue to direct the completion of site clearance in May 2021 according to the province’s progress; Early completion of related procedures to ensure a dumping site for project construction. Regarding the handling of materials for construction, the Chairman of the Economic Committee of the National Assembly requested the Ministry of Transport to review the material needs of the entire route, directing the Project Management Boards to: Thang Long, 7, 85 urgently coordinate with the province to remove problems.
