Accordingly, on May 28, the Australian Federal Foreign Investment Commission (FIRB) approved the contract to buy 100% of the shares of the Roper Valley iron ore mine project of the Australian subsidiary of Hoa Phat Group. . Roper Valley iron ore mine has estimated reserves of 320 million tons. After the transaction is completed, Hoa Phat is the owner of the Roper Valley iron ore project with an estimated reserve of 320 million tons and a mining capacity of 4 million tons/year. Hoa Phat said that the group will continue to research to invest in buying some new iron mines in Australia, in order to ensure a long-term supply of at least 50% of the Group’s iron ore demand (equivalent to 10 million tons of iron ore). /year). Besides, the raw material that constitutes up to 30% of the steel price is coking coal, which is currently imported by Hoa Phat from Australia – the world’s largest coking coal supplier market. The Group is studying to buy a few Australian coking coal mines in the future to gradually become self-sufficient in this important production material. Talking to Dat Viet, metallurgical expert – Prof. Dr. Pham Pho assessed, this step of Hoa Phat is very wise, helping businesses to proactively source raw materials in a stable and long-term way. According to him, normally Australia rarely sells the whole mine, but now, due to political and trade tensions with China, Beijing has limited the purchase of iron ore from Canberra, on condition that Australia sells the whole ore mine to Vietnam. should be easier without raising prices. Roper Valley iron ore mine has estimated reserves of 320 million tons. Photo: Hoa Phat “With this step, Hoa Phat can take the initiative in the source of raw materials, only have to worry about exploitation and transportation. Enterprises must send people to supervise and operate, along with a team of workers in your country to exploit. Most of Vietnam’s steel mills rely on scrap iron for production. However, the current scrap iron and steel is limited, the price has increased, the quality is poor, not to mention the difficulty in transportation. It can be said that enterprises producing steel by electric furnace technology, using scrap iron will face many difficulties in the future. Therefore, this step of Hoa Phat is very important,” said Professor Pho. The expert also highly appreciated Hoa Phat’s plan to buy coking coal mine. However, he also noted, buying coal mines to produce coke is very difficult, the production process of coke costs a lot of money. Therefore, it is often easier for a business to cooperate with a partner in Australia than to be completely self-sufficient. “Of course, businesses choose depending on specific conditions to produce coke. To produce coke, it is necessary to use fat coal, not coal. The carbon content in it is high and contains a certain amount of oil. When heated, , the amount of oil evaporates, leaving pores. These pores will make the air flow, not clogged and it will provide fuel continuously. If the business can buy ore mines, and at the same time associate with partners in Australia to produce coke, it is very good. This depends on the operating ability of the business, if you want to produce cups, you must have good experts, and ore is simple – just dig, treat and bring back. If the direction of the business is to buy coke mines, then transporting coke to Vietnam, coking production in Vietnam is better and also simpler, because the production process of coking coal has many other products. For example, when coking, the gas that rises contains a lot of fuel, in which CO is very high, gives high value of electricity, provides for the process of electricity production, boiler heating…”, Prof. TSKH Pham Analysis Street. He also noted that producing steel from ore has a more complicated process than producing steel from scrap (iron scrap) and is also cheaper. The quality of steel depends on the manufacturing process. Even scrap steel wants to produce good steel, it must be carefully selected and classified. Currently, scrap steel in the world is still small, with many impurities. When buying, manufacturing enterprises must carefully select and classify, which costs a lot of money. Regarding the problem of environmental pollution treatment, Professor Pho said that blast furnaces are more complicated than electric furnaces that use scrap iron and steel. When the blast furnace emits gas, it is necessary to invest in equipment to recover coal dust for reuse. Similarly, the exhaust gas contains a lot of CO, which if left to fly into the environment is very toxic, so it must be recovered to put back to burn in electric furnaces or furnaces. This does not mean that electric furnaces do not have to deal with environmental pollution. The electric furnace itself must also be equipped with equipment to capture waste gas, coal dust and filter. Because technology and equipment to deal with environmental pollution are very expensive, according to Prof. Pho, it is important whether steel factories are willing to invest or not.

1. Where is the latest named ocean? Icon Atlantic Icon Indian Ocean Icon southern Ocean The correct answer is answer C: The Southern Ocean is the newest ocean to be named. Previously, the Atlantic, Pacific and Indian Oceans were considered to extend as far as Antarctica, the name Southern Ocean did not exist. According to the National Ocean Service. The Southern Ocean is recognized by the US Organization of the US Board on Geographic Names as the water stretching from the Antarctic coast to the 60 degree south latitude line. The boundary of this ocean was proposed to the International Hydrological Organization (IHO) in 2000. This ocean name is widely recognized, however some organizations disagree. The Southern Ocean is 20.3 million square kilometers wide, equivalent to the area of ​​Russia and India combined. Coast stretches for nearly 18,000 km. The average depth is 4,000 – 5,000 m. The deepest point is in the South Sandwich Trench with a depth of 7,236 m. 2. Which ocean is the largest and the deepest? Icon Indian Ocean Icon Pacific Icon Atlantic The Pacific Ocean is the largest and deepest ocean on Earth. With an area of ​​165.25 million km2, this ocean accounts for one third of the total surface area of ​​the globe. All the land on Earth combined (about 150 million square kilometers) still cannot cover the surface of this ocean. The Pacific Ocean stretches from the Arctic Ocean in the north to the Antarctic continent in the south. The widest east-west width is 19,800 km, separating Asia, Oceania from the Americas. The Pacific Ocean has an average depth of 4,280 m. The deepest point of the ocean lies in the Mariana Trench, 10,911 m deep. This is also the deepest point of the Earth’s crust, 13 times the height of the Burj Khalifa – the tallest building in the world in Dubai. If Everest could be placed on the bottom of the Mariana Trench, the world’s highest mountain would still lie underneath the Pacific Ocean. 3. Which ocean is the smallest? Icon southern Ocean Icon Atlantic Icon Arctic Ocean The correct answer is answer C: According to the National Ocean Service, the Arctic Ocean is the smallest ocean on Earth with an area of ​​nearly 14.1 million square kilometers. Even the smallest, it is still nearly 1.5 times larger than the US. The Arctic Ocean borders the United States (the Alaska region), Russia, Canada, Norway and Denmark (the Greenland region). The average depth of this ocean is about 1,205 m, the deepest point is 5,567 m. The Arctic Ocean is almost completely covered by ice most of the year. However, this ocean is not barren. When the ice melts, organisms and nutrients are released into the water. This promotes the growth of algae under the ice. These algae provide food for small organisms, zooplankton, and are a source of food for fish, squid, seals and whales. Some of these larger creatures become prey to polar bears. When the organisms under the ice die, they sink to the ocean floor and feed sponges, anemones and other bottom organisms. 4. Is the Atlantic Ocean larger than the Indian Ocean, right or wrong? Icon It’s correct Icon Wrong The correct answer is answer A: Kindy Data already has a comparison showing that the Atlantic Ocean has an area larger than the Indian Ocean. The Atlantic Ocean is 106.5 million square kilometers wide, covering 20.8 percent of the Earth’s total surface. The average depth is 3,646 m. The deepest point is in the Puerto Rico Trench, at 8,486 m deep. It is surrounded by America to the west, Europe and Africa to the east. The width from east to west is about 9,600 km. Meanwhile, the Indian Ocean is 70.56 million square kilometers wide, covering 13.8 percent of the Earth’s surface. The average depth is 3,963 m. The deepest place is Diamantina trench, 8047 m deep. To the north, this ocean is limited by peninsulas India, Pakistan and Iran, east by Southeast Asia (namely Myanmar, Thailand, Malaysia, Indonesia) and Oceania, to the west by Arab and African islands. The Indian Ocean opens in the south and is bordered by the Southern Ice Ocean. 5. How many tons of gold does the world’s oceans contain? Icon 10 million Icon 20 million Icon 30 millions The correct answer is answer B: Experts estimate that about 20 million tons of gold are still in the ocean. Experts confirm that 1 ton of ocean ore contains about 13 grams of gold, while on land, only 3 to 7 grams of gold per ton of ore. 6. In which sea area is volcanic activity concentrated? Icon South Pacific Icon Indian Ocean Icon Atlantic The correct answer is Answer A: 90% of all volcanic activity on earth is concentrated in the ocean with the largest concentration in the South Pacific. 7. What is the freezing temperature of the oceans about Celsius? Icon -10 degrees C Icon -5 ° C Icon -1.8 degrees C The correct answer is Answer C: Seawater freezes around −1.8 ° C (28.8 ° F). When the temperature of the water drops low enough, ice crystals form on the surface. 8. Which ocean contains the highest salt content in the world? Icon Pacific Icon Atlantic Icon Indian Ocean The correct answer is answer B: Which ocean is the most salty in the world? that is the Atlantic Ocean. In this barn, the average salinity is about 37.9 o / oo. In the Sargasso Sea in the North Atlantic Ocean is the region with the greatest salinity. The reason is that the temperature here is quite high and located far from the mainland, so it does not receive water from rivers and streams. The lightest seawater belongs to the Arctic and Antarctic regions. This is understandable, these are 2 areas with low temperature and continuous rainfall and ice melting.

An old phosphorus mine in Florida.

According to information from the BBC, China uses rare earths as a trump card in the trade war with the US. China has signaled that it could limit exports of rare earth minerals to the US as the trade conflict between the two countries escalates.

By far, China is the largest producer of raw materials vital to many US industries including high-growth industries such as electric vehicles and wind turbine manufacturing. The US Geological Survey has determined these minerals are very important to the economy and defense of this country.

Restricting exports to the US, if implemented, could have a major impact on major US industries worth trillions of dollars that rely on rare earth minerals.

Rare earths are a valuable resource that plays an important role in the industry.

Rare earth is a group of 17 elements used in many fields, including renewable energy technology, oil refining, electronics, … Called “rare” because they are difficult to exploit. This raw material is believed to be in the Earth’s crust. There are very few places in the world that exploit or produce rare earths because rare earth exploitation is both difficult and potentially harmful to the environment.

Rare earth exploitation is very difficult and poses a risk to the environment.

Currently, Chinese mines account for about 70% of global rare earth production. Myanmar, Australia, the US and some other countries only exploit a small amount, accounting for the remaining 30%.

According to US government data, about 80% of imported rare earths come from China. Estonia, France and Japan also supply treated rare earths to the US, but the original ore is from China.

The US mines rare earths and sends ore to China for processing, but China has imposed a 25% import tax. Consequently, the United States considered developing its own rare earth refining industry.

Information from the New York Times and Bloomberg said that the US is seeing the potential to exploit rare earth from old phosphorus mines in Florida. The process of handling leaked waste here helps to protect the environment and is an opportunity to reduce dependence on rare earths from China.

China is holding back most of the world’s rare earth supply.

A sewage leak at an old phosphorus mine in Florida prompted authorities to issue an evacuation order and declare a state of emergency near the Tampa area amid a potential collapse of the mine’s radioactive waste. Cleaning up the forgotten giant pile of phosphorus scattered in Florida and other parts of the southeastern United States could help resolve America’s dependence on important imported raw materials, while eliminating Threats of environmental disaster are lurking in the local people.

Phosphorus is a byproduct of the production of fertilizers from phosphate rock. For every ton of organic phosphoric acid produced, more than five tons of phosphorus are produced. This waste is worthless in its raw form due to the concentration of uranium, radium and other heavy metals making it radioactive toxic, unable to be used as soil amendment or building material.

According to the study, there is a large amount of rare earths and radioactive metals present in phosphorus piles in Florida. However, those are not the only scarce metals that can be found in phosphorus ores. Rare earths are a collection of elements that are important for high-tech applications such as magnets and lasers. A 2017 analysis by the US-China research group showed that rare earths are present at a rate of about 0.2% in a waste pile of about 1 billion tons in Florida, equivalent to two million tons of rare earths, enough to cover global demand for a decade.

Many laboratory studies have been done to look at phosphorus recycling processes. However, prices for phosphorus, rare earths and uranium have been mostly curbed in recent years to limit the commercial appeal of phosphorus recycling around the world.

Every year, the US government spends a substantial amount of money monitoring and managing risks at the old phosphorus mine in Florida. The US plans to spend about $ 111 billion to clean water pipes and water infrastructure.

Under the Donald Trump administration last year, the US environmental protection agency authorized the use of raw phosphorus as road construction materials. However, the cost of waste treatment here is so high that investors are still afraid.

The US government has to spend a lot of money on the treatment of the phosphorus mine in Florida.

Huge open-pit ponds the size of the entire city block, filled with toxic wastewater, and underneath there is a lot of radioactive waste.

Recently, local officials allowed residents to return home after an urgent effort to pump millions of gallons of water out of ponds and into inland waterways. The environmental impacts of releasing large amounts of polluted water have not been evaluated. But in the past week, the “ghost” of a great cataclysm caused the government to evacuate hundreds of households from the dangerous area.

Researchers fear that, when giant puddles collapsed, radioactive waste will leak, it will lead to unpredictable dangers. The environment will be affected by the emergency discharge of polluted water, which contains many substances that can cause harmful algae to bloom and kill fish.

Wastewater in the area near Wilmington in North Carolina.

Florida is considered the largest producer of phosphorus in the world, accounting for about 80% of phosphorus mining in the US – where the exploitation and consumption of about 23 million tons of phosphorus per year.

When coal-fired power plants generate electricity, they leave hundreds of thousands of tons of toxic sediment known as coal ash, mixed with water and dumped into ponds within the plant.

Across the United States there are more than 700 landfills and large bodies of water still store coal ash discharged from coal-fired power plants. Under the Obama administration, there were regulations to close coal ash ponds in 2018. Currently, the North Carolina region authorities also began requiring power companies to dig coal ash ponds under the new law. state, also requiring the closure of all coal ash ponds by 2029./.
