The country with the largest rare earth reserves in the world is China.
China is the largest country with absolute rare earth reserves. It is not only rich in rare earth resources, but also has the advantages of complete minerals and rare earth elements, reasonable rare earth grade and ore point distribution.
Rare earth is known as industrial "gold". Because of its excellent physical properties such as photoelectric and magnetic properties, it can form new materials with different properties and a wide variety with other materials. Its most significant function is to greatly improve the quality and performance of other products.
For example, greatly improve the tactical performance of steel, aluminum alloy, magnesium alloy and titanium alloy used to manufacture tanks, aircraft and missiles. Moreover, rare earth is also a lubricant for many high-tech industries such as electronics, laser, nuclear industry and superconductivity.
Moreover, the molecular sieve catalyst made of rare earth has the advantages of high activity, good selectivity and strong resistance to heavy metal poisoning, so it replaces aluminum silicate catalyst in petroleum catalytic cracking process; In the process of synthetic ammonia production, a small amount of rare earth nitrate is used as cocatalyst, and the treatment gas volume is 1.5 times larger than that of nickel aluminum catalyst.
