The European Commission issued a report entitled "Materials for the Life and Death of the European Union", proposing early warning and countermeasures for the shortage of rare mineral raw materials in the EU. Based on the analysis of the economic impact and supply risks of 41 mineral resources, the report listed 14 important mineral raw materials in the “short shortage” list. The 14 mineral raw materials are: lanthanum , cerium , cobalt , fluorite , gallium , germanium, graphite, indium, magnesium, niobium, platinum group metals, rare earth (including scandium, yttrium and lanthanide rare total of 17), tantalum, and tungsten. These materials are widely used in the manufacturing process of mobile phones, lithium batteries, fiber optic cables and solar panels, and are an integral part of many high-tech products and consumer products. The report believes that the shortage of rare mineral raw materials may affect the development of the EU high-tech industry and even the EU low-carbon economy. The scarcity of rare mineral raw materials is mainly caused by three factors: First, the supply of these rare mineral raw materials mainly comes from a few countries, and second, these rare mineral raw materials are difficult to replace and are not easy to recycle, which further aggravates their supply. safe question. Third, the development of new technologies and emerging industries has led to a rapid increase in demand for these raw materials. For example, gallium is widely used in thin-film solar photovoltaic cells, and without cobalt, lithium batteries will not be able to conserve energy. The report estimates that demand for these raw materials is expected to triple in the next 20 years.

In the “12th Five-Year Plan” draft of China's non-ferrous metals industry, by 2015, the output of ten non-ferrous metals ( copper , aluminum , lead , zinc , nickel , tin , antimony, magnesium, sponge titanium , mercury ) will be controlled within 41 million tons. This move will push up the price of rare small metals.

Rare light metals include lithium, strontium , barium , and strontium. Small specific gravity and strong chemical activity. Rare refractory metals include titanium, zirconium , hafnium , vanadium , niobium, tantalum, molybdenum , and tungsten. The melting point is higher, and the melting point of compounds formed with carbon, nitrogen, silicon, boron, etc. is also higher. Rarely dispersed metals are referred to as rare metals, including gallium, indium, antimony , bismuth, antimony, and selenium and tellurium . Most of them are found in minerals of other elements. Rare rare earth metals are referred to as rare earth metals, including lanthanum, cerium and lanthanides. Their chemical properties are very similar and are associated with each other in minerals. Rare radioactive metals include lanthanum, cerium , lanthanum, uranium in naturally occurring lanthanum, radium, radon and lanthanide metals, as well as other elements of lanthanum, cerium, lanthanide and elements 104 to 107.

Indium: China's reserves rank first in the world. It accounts for 80% of global supply. Mainly used in flat panel displays, alloys, semiconductor data transmission, aerospace products manufacturing. Mainly associated with lead-zinc mines, China's primary indium production in 2005 was only 410 tons. Indium It is an associated metal, it is only the content of zinc concentrate is calculated by PPM (million), very little, can not be regenerated.

Tungsten: China's world reserves are the first. It accounts for 85% of global supply. Mainly used in hard alloys, special steel and other products, and is widely used in the defense industry, aerospace, information industry, known as "industrial teeth." It can withstand high temperatures, so tungsten alloys are widely used in machinery and weapons industries. For example, alloys of tungsten are used in the launch tubes of guns and guns. The projectiles used by the military for armor-piercing projectiles are made of high-density alloy steel, tungsten carbide and other materials that are much harder than tank armor. The mechanical properties of tungsten alloys are similar to those of depleted uranium, and the disadvantages of depleted uranium are its advantages. Tungsten is not radioactive, its chemical properties are very stable, it will not oxidize even at high temperatures above 1000 °C, and the hardness will not drop significantly. This is very advantageous for the high-temperature metal jet of the armor-resistant projectile. The high hardness of tungsten, an alloy mainly for steel metal, there is added a hardness of tungsten steel greatly improves the tool material in the metal processing art high-speed steel is an alloy containing tungsten. If a country does not have tungsten, the metal processing capacity under the current technical conditions will be greatly lacking, which directly leads to the paralysis of the machinery industry, so it is called a strategic metal. In addition, tungsten must be used as a filament in the field of lighting.

Molybdenum: China's reserves rank second in the world. Accounting for 24% of global supply. It is used in the refining of various alloy steels, stainless steels, heat-resistant steels and super-alloys. It is widely used in the military industry and is called "war metal".

Rare earth: China's reserves rank first in the world. The supply accounts for more than 80% of the global total. Used in the manufacture of composite materials, alloy materials such as magnesium, aluminum, titanium, etc., is analogously referred to as "industrial MSG.

é”—: Reserves rank first in the world. Production accounts for 50% of the world. It is mainly used in the production of night vision devices, thermal imagers, petroleum product catalysts, solar cells, etc., and is widely used in the field of optical fiber communication.

Titanium: Titanium and titanium alloys are widely used in the aerospace industry and are known as "space metals". In addition, they are increasingly used in the shipbuilding industry, chemical industry, manufacturing machinery parts, telecommunications equipment, and hard alloys. In addition, titanium alloys can also be used as artificial bones because of their good compatibility with the human body.

Vanadium: The metal with the highest melting point is more than 3,000 degrees Celsius. Vanadium is used in steel because vanadium can form a stable carbon compound (V4C3) with carbon in steel. It can refine the structure and grain of steel and increase the temperature of coarse grain. Significantly improved performance in improving steel. It can increase the strength, toughness, corrosion resistance, wear resistance and ability to withstand impact loads of steel.
