The Change of World Rare Earth Industrial Structure and the Problems Faced by China's Rare Earth Industry |
Rare earth elements have been widely used in new materials such as permanent magnet materials and are listed as strategic resources by major countries in the world. From the perspective of resource and production pattern, in recent years, with the emergence of the worldwide rare earth exploration boom and the massive mining of China's rare earth resources, China's dominant position in rare earth resources has been gradually decreasing. The United States and other Western countries are vigorously promoting the construction of rare earth mines and smelting and separation projects outside China, which may change the global rare earth production pattern. From the perspective of consumption, the consumption of rare earth can be classified into eight final uses, such as permanent magnet materials and catalysts. Permanent magnet materials and catalysts have accounted for 60% of the consumption of rare earth, while permanent magnet materials have accounted for 91% of the consumption value of rare earth. China and Japan are the world's largest consumers of rare earths, followed by the U.S. and European countries. After years of development, China has become the only country in the world with a complete rare earth industry chain. However, in the process of development, China is also faced with the problems such as lack of pricing power for rare earth products, rapid consumption of resources, and being disciplined by others in high-end materials and application technologies. In view of the problems faced by China's rare earth industry, this paper puts forward some suggestions, such as strengthening the research and development of rare earth products and application and building a mining aircraft carrier for the rare earth industry. |
