 Trump ordered the expansion of rare earth mining on the ground of Chinas threat


Trump signed an executive order to address the threat of reliance on foreign key minerals on domestic supply chains, instructing the U.S. Department of the interior to explore the use of the defense production act to speed up mine development, according to Reuters on October 1. In novel coronavirus pneumonia, the US government has accelerated the production of medical supplies. Reuters said the rare earth administrative order could lead to tariffs, quotas or other possible import restrictions.

Trump signed the order on his way to Minnesota, where he hopes to win the support of miners and residents in iron range for his re-election, according to the U.S. Bloomberg News Agency.

Key minerals have always been the focus of attention in the United States. According to the text of the rare earth administrative order released by the White House, 80% of the total imports of rare earth compounds and metals in the United States came from China last year. Although the United States was once a major producer of rare earths, Chinas influence in the rare earth industry has played an important role in Sino US trade disputes, Reuters said.

In 2019, trump asked the U.S. Department of defense to find better ways to obtain samarium cobalt rare earth permanent magnets, which are often used in precision guided missiles, smart bombs and military aircraft. Two U.S. Republican senators have proposed separate mineral related legislation in the past year, but they have not yet been passed.

Geng Shuang, then spokesman of the Chinese Ministry of foreign affairs, once said at a regular press conference last year that it would not be feasible to dominate or monopolize a certain field or market, or to artificially cut off or exclude a certain chain in the era of globalization.

Geng Shuang pointed out that China has always adhered to the principle of openness, coordination and sharing to promote the development of domestic rare earth industry. China is willing to use rare earth resources and products to meet the legitimate needs of the development of all countries in the world and play a positive role in promoting the development of Chinas economy and the world economy.

Today, lets talk about the popular rare earth. What does rare earth look like? Its what we call yellow earth grain. Its full of big holes and small eyes. But its such a humble thing. Its called industrial vitamin. Ill talk about its important role in weapons later. Well be more surprised. In the public opinion field of China and the United States, many people say that it is Chinas Assassins mace, and its important role is almost irreplaceable.

Lets start with the name Assassins mace today.

As we all know, there are 18 kinds of weapons in China. They are: swords, spears, halberds, axes, axes, hooks, forks, cudgels, swords, swords, axes, axes, hooks, forks, sticks, swords, maces, maces, and hammers, it is said that there are 18 kinds of weapons in China. Among them, whip, mace and hammer are one kind of blunt weapons and heavy weapons. According to the system of the Song Dynasty, mace is 1.2 meters long. It is made of refined iron. There is a handle on the bottom. On the top is an iron stick with four sides, that is to say, it has four edges. According to textual research, the single mace should be more than 20 jin. If it is used by people with infinite strength, it may be close to 100 Jin. Why? Because mace is different from sharp weapons such as swords and spears, it has no edge and no point. It relies on a strong blow. Its useless if its light.

But it also has a problem, that is, a horse carries a variety of armor and equipment, up to 78 kg, which is not the weight of a person. This makes the mobility of heavy armour cavalry very poor. During the peasant war at the end of the Sui Dynasty, Li Yuan and his son set out to attack. In their army, there was a light cavalry from Western Turks. They went around behind the heavy Armored Cavalry of the Sui army to launch attacks, and they won many battles. In the Tang Dynasty, light cavalry replaced heavy Armored Cavalry. You can think of the relief of the six steeds of the Zhaoling Mausoleum of Li Shimin, Emperor Taizong of the Tang Dynasty. These horses are not armored. And among them, Zhui was shot with five arrows and Qu u00e1 nm u00e1 Ogu u0101 with nine arrows. We can imagine the intensity of the war at that time. Lets talk about it again. Although the Tang army was good at using light cavalry, with the development and progress of technology, especially the introduction of foreign armor, the protection ability of Tang Dynasty armor was still very strong.

So why did mace become popular in this period? Because it has a core function, is to hit the enemy protected by armor. In the battlefield, guns are used to pierce, knives are used to scratch, and Maces and hammers are used to smash. In the face of people and horses wearing heavy armor, sharp weapons cant make them strong, but maces and hammers, with their own weight, combined with the strength of the users arm and the inertia brought by the horses, can penetrate the armor with a great force and break peoples muscles and bones. This is the first feature of mace, which is specially used to deal with heavy armor.

Mace -- the symbol of loyalty

Another feature of mace is that at the cultural level, it symbolizes loyalty. Lets see who is using mace. The first one was Qin Qiong and Qin Shubao in Sui and Tang Dynasties. He used the double mace, and he was brave. It is known as the mace strikes both sides of the Yellow River, and the horse steps on half of the sky in Shandong Province; it is also known as SaiMeng taste and like Zhuangzhu, which means that this person is filial to his parents and extremely loyal to his friends. In the Sui and Tang Dynasties, when 46 friends of Jias house were worshipped, Qin Qiong ranked second and was honored as the second Lord of Qin. So Shandong man used to have a honorific title called Er Ye. No matter who he is, he will be happy if he is called second master.

Yue Feis expedition

Here leads to another problem, that is, we often say Assassins mace and Assassins mace. The history of this thing is uncertain. In my opinion, mace is used for surprise attack when conventional weapons cannot win. For example, you can block the opponents weapons with long weapons, and then smash them with mace to make them unprepared. Or throw the iron bar at each other when fighting or pretending to be defeated. Its unlikely that you only have a mace in your hand and throw it out.

There is the third feature of mace, that is, sudden attack and fatal strike.

Lets go back to loyalty. I dont need to introduce Yue Fei. We all know this famous general and national hero very well.

In fact, there is a man with a mace in his hand. Thats Zhao Defang. Todays young friends may not know that there was such a prince with a golden mace in Pingshu Yang Jiajiang and three swordsmen and five righteousness. He defeated the emperor at the top and slandered the minister at the bottom. He often used gold mace given by the emperor to protect Yang Jiajiang and Bao Zheng. He was the fourth son of Zhao Kuangyin, Emperor Taizu of Song Dynasty. However, his story is fictitious. He died at the age of 22.

So why is mace a symbol of loyalty?

Mace and rare earth

You may wonder why rare earth has been talking about cold weapons for such a long time. I think there are two reasons

The second reason is more important. That is, I hope that everyones way of thinking can be similar and interconnected. The knowledge and skills we learn are all one by one. We should connect them into lines, and then connect them into surfaces. Only in this way can we discover the wonder of the world, we can see through the problems, and we can sit firmly on the Diaoyutai despite the wind and waves.

How important are rare earths?

Now, lets talk about rare earth. Rare earth is the general name of 15 lanthanide elements and 17 metal elements of scandium and yttrium in the chemical periodic table. As a strategic scarce resource, its unique physical and chemical properties make it have optical, electrical and magnetic properties that many other elements do not have.

Lets talk about how important rare earths are. I think what comrades are most interested in are the cutting-edge weapons in the United States that use rare earths. So the F-35 fighter, the Virginia class nuclear submarine, the Tomahawk cruise missile, the guidance system, and jet engines all need rare earths. From propulsion motors of large ships to small chips on missiles, from precision optical instruments to rough looking gun tubes, the application of rare earth elements will greatly improve their performance.

Modern information equipment is inseparable from chips, and the manufacturing of chips can not do without rare earth elements. To a great extent, it depends on the chip that the precision of attacking is not accurate, the detection distance is not far, the anti-jamming ability is not strong, and the reaction speed is not fast.

The electric motor is a necessary equipment for many high-tech equipment. The electric propulsion system of a 10000 ton warship and the generator on a missile are inseparable from the motor. Rare earth elements can improve the performance of the motor obviously. Rare earth permanent magnet is called super permanent magnet because of its superior magnetic properties. It is small in size, light in weight, simple in structure, reliable in operation and high in heat dissipation efficiency. Almost all the air-to-air and air-to-ground missiles in the United States use rare-earth permanent magnet motors to control the rudder surface. The permanent magnet mentioned here is permanent, the magnet of magnet. This thing can not keep the original magnetic state unchanged forever, but its magnetism is relatively stable and its decay period is relatively long.

Rare earth elements are also widely used in optical devices. At present, most laser materials involve rare earth elements, ranging from laser rangefinder, lidar to laser guided weapons. For example, the main battle tanks in western countries, such as M1 series, leopard 2 series and Challenger series, are equipped with a laser rangefinder, in which rare earth elements are used. Laser guided weapons, such as laser guided bombs, laser guided shells and so on, also rely on the use of rare earth element laser irradiator to irradiate the target. Rare earth luminescent materials have also been successfully used in night vision devices.

Rare earth elements can also be used to make absorbing materials for stealth aircraft. Ferrite material is an important invisible coating for aircraft. In addition, rare earth materials can be used in nuclear radiation shielding, and used in nuclear reactors, sonar and other aspects.

From the importance of rare earth in the field of military industry, we can see its importance in the field of civil industry. In large areas, the information technology industry, high-end CNC machine tools, robots, aerospace equipment, marine engineering equipment, high-tech ships, advanced rail transit equipment, energy-saving and new energy vehicles, electric power equipment and so on are highly related to rare earth.

Rare earth can be replaced in some fields, but not in some industries. For example, in the fields of military materials, new energy vehicles, wind power, smart phones, chips, etc., it is really impossible to leave rare earth elements

Take automobiles as an example, it will be difficult for the whole industry to leave rare earth, especially new energy vehicles. We usually use NdFeB permanent magnets in dozens of parts of every car, such as engines, brakes, sensors, meters, speakers, etc. A full-automatic high-class car consumes about 0.5-3.5 kg of rare-earth permanent magnet materials, while the application of NdFeB materials in new energy vehicles will be more, reaching 10-20 kg. It can be said that the development of high-tech society without rare earth elements is unimaginable.

The distribution of rare earth elements in China is light in the north and heavy in the South. The light rare earth deposits are mainly distributed in Baotou, Inner Mongolia and Liangshan, Sichuan. The ionic medium heavy rare earth deposits are mainly distributed in Ganzhou, Jiangxi and Longyan, Fujian. Medium and heavy rare earth, with rare total content and high use value, is mainly used in national defense and military industry and high-end fields.

Our reporter once visited the rare earth enterprises in Ganzhou. We have a comprehensive understanding of the present situation of rare earth in our country.

First of all, China is a big country of rare earth resources. According to the data of the US Geological Survey in 2019, the global rare earth reserves are 120 million tons, including 44 million tons in China, 22 million tons in Vietnam, 22 million tons in Brazil, 12 million tons in Russia, 6.9 million tons in India, 3.4 million tons in Australia, and 1.4 million tons in the United States.

At present, China is the country with the largest reserves, production and exports in the world. In 2018, China exported 53000 tons of rare earth, with a total export amount of about 3.39 billion yuan. According to other data, from 2014 to 2017, 80% of the total rare earth imports of the United States came from China. In the field of permanent magnet materials, the worlds demand is 160000 tons of rare earth per year, and Chinas annual supply can reach 140000 tons.

Second, we have both advantages and disadvantages in rare earth technology. The advantage is that China has formed a complete rare earth industrial system. At the level of science and technology, China has developed a number of internationally advanced technologies in the fields of rare earth mining, smelting and separation. In rare earth separation and extraction technology, China has incomparable advantages over other countries. Our rare earth separation purity has been over 99.9999% for a long time. So, why cant the United States have rare earth mines? Because the technology of separation and purification is in the hands of China.

So what are our weaknesses? Thats the core technology of high-end applications. In terms of core patents, there is still a big gap between China and developed countries. For example, Chinas largest consumption of NdFeB rare earth permanent magnet materials, all core patents are in the hands of Japanese and American companies. Therefore, Chinas rare earth industry is a big country in terms of output and consumption, but technically, it is not a powerful country. This is similar to that in rural areas, although grain raw materials are produced, the real high-end food still needs to be purchased from urban food processing plants, and the main profit and added value are still in the industrial link of deep processing.

Nevertheless, Chinas rare earth industry still has a strong voice, and our rare earth policy has a strong influence on the international market. However, with the increase of rare earth mining in other countries, China is facing new challenges in maintaining its influence.

Third, based on the current Sino US relations, the United States has a deep uneasiness on the rare earth issue. In fact, there are rare earths in the United States, but they are basically light rare earths, which can not be used in military industry and high technology. Therefore, since 2019, the U.S. Department of state, Department of defense, and Department of Commerce have successively sent missions to Canada, Australia, Mongolia and many African countries to contact and build rare earth mining and processing plants. Australias largest rare earth mining company will build factories in the United States. At the end of July last year, trump met with the Mongolian President in Washington. The two sides discussed U.S. mining investment in Mongolia, including rare earth elements. In addition, the Financial Times said that trump had proposed to buy Greenland. Although the idea seems ridiculous, the United States is actually targeting the resources there, especially rare earths. The US Senator Rubio, known as the vanguard of Anti China, proposed to establish a Rare Earth Alliance not bound by the anti-monopoly law.

The U.S. military is even better, and directly pays for rare earth enterprises to build factories in the United States. But the latest news is that the U.S. military has stopped these investments. Some technical bottlenecks can not be found in a short period of time. A professional told our reporter that it will take at least three years to rebuild the rare earth industry chain in the United States.

After talking about the above contents, I think you can have a comprehensive and objective understanding of rare earth.

So what do I want to say in the end? That is, in the eyes of Americans, rare earth should be the sword of Damocles hanging over their heads. In our opinion, its a high-rise mace. Its right there if its smashed or not. What we should do now is to tackle key problems in core technologies and use more and precious rare earth resources in our high-tech weapons and civilian products. Only in this way will the sword edge become sharper and sharper, and the assassins mace will become heavier and heavier
