One of the characteristics of China's non-ferrous metal resources is that there are many composite minerals, and some have lower grades. Not only many non-ferrous metals are often symbiotic, but some iron ore also contains a large amount of non-ferrous metals. For example, Panzhihua iron ore contains a large amount of vanadium. Titanium; Baotou iron ore contains a large amount of rare earths and strontium. Therefore, it is a very important task to develop new technologies, new processes, new equipment and new materials suitable for China's resource characteristics. It is a future task to establish a non-ferrous metal material system suitable for China. .
China's non-ferrous metals are rich in resources and the varieties are relatively complete. As far as we know, the reserves of seven metals such as tungsten and rare earth rank first in the world; the reserves of five metals such as lead, nickel, mercury, molybdenum and niobium are also quite abundant. Among mineral resources, non-ferrous metals are a major advantage for China. Before the founding of the People's Republic of China, China's non-ferrous metal industry was very backward. No matter the mine or factory, its equipment is very small. It can only produce gold, silver, tin, antimony, copper, lead, zinc, mercury, etc. Many non-ferrous metals can't. produce.
Since 1949, China's non-ferrous metal industry has developed rapidly, and has formed a production system from common non-ferrous metals to rare metals, with relatively complete varieties and relatively complete processes. China's various non-ferrous metals mining, mineral processing, smelting and processing plants are quite large, but there is still a certain gap compared with the world's advanced level. To this end, while carrying out the construction of new mines and factories of non-ferrous metals, it also faces the technical transformation tasks of existing mines and factories to give full play to the advantages of China's non-ferrous metal resources and meet the needs of national economic development.
