Non-ferrous metals are essential basic materials and important strategic materials for the national economy, People's Daily life, national defense industry, science and technology development. Agricultural modernization, industrial modernization, national defense and science and technology modernization are inseparable from non-ferrous metals. For example, aircraft, missiles, rockets, satellites, nuclear submarines and other weapons, as well as atomic energy, television, communications, radar, electronic computers and other technologies required components or components are mostly made of light metals and rare metals in non-ferrous metals; In addition, without nickel, cobalt, tungsten, molybdenum, vanadium, niobium and other non-ferrous metals, there is no alloy steel production. Non-ferrous metals in some uses (such as the power industry, etc.), the use is also considerable. Many countries in the world, especially industrially developed countries, are competing to develop non-ferrous metal industry and increase the strategic reserves of non-ferrous metals.

Today, non-ferrous metals have become an important material basis for determining the development of a country's economy, science and technology, and national defense construction, and are key strategic resources for enhancing the country's comprehensive strength and safeguarding the country. As a large non-ferrous metal production country, China has made great progress in the field of non-ferrous metal research, especially in the development and utilization of complex low-grade non-ferrous metal resources.
