Extended data
Tantalum-niobium ore refers to the general name of minerals containing tantalum and niobium, and there are more than 100 kinds of * * *. Among them, tantalite, niobite and pyrochlore are the main minerals that can be mined. Tantalum (Ta) and niobium (Nb) are rare metals with high melting points (Ta is 2996℃, Nb is 2468℃) and high boiling points (Ta is 5427℃, Nb is 5 127℃). They are steel-like, gray-white, with dark gray powder, and have the characteristics of gas absorption, corrosion resistance, superconductivity, monopole conductivity and high strength at high temperature.
For a long time after the founding of New China, the capitalist countries blockaded and embargoed China with rare rare rare earth metal minerals such as lithium, beryllium, niobium and tantalum as strategic materials, so the country decided to solve the mineral resources and develop the rare rare rare earth metal industry in China on its own. A number of large and super-large deposits were quickly identified, such as super-large and medium-sized lithium beryllium tantalum niobium deposits such as Fuyunketuohai, Krumut, Qinghe Achkar Te, Fuhai Cuokagai and Fuhai Qunkuer, and super-large niobium rare earth deposits such as Bayanobo in Inner Mongolia.
Sichuan Kangding Methyl Cat Large Lithium Beryllium Mine, Jinchuan Kelin Large Lithium Mine, Yiliping in Qaidam Basin of Qinghai, Jinaier Lake in Dongxitai, etc. , Jiangxi Hengfeng Huangshan large-scale tantalum-niobium mine, Guangdong Zengcheng Paitan large-scale niobium-iron mine, Boluo large-scale tantalum-niobium mine, Guangxi Guposhan large-scale fergusonite, Gongcheng Limu Hutou medium-sized tantalum-niobium mine, Hunan Xianghualing beryllium mine, etc., after the 1970s, on the basis of large-scale prospecting in the 1950s and 1960s, a number of deposits were discovered and explored.
