North, northwest and southwest have output, especially in the west, Guangxi, Hunan, Guangdong, Jiangxi, Fujian, east Nanling Mountains area, tungsten ore. Among them, the southern part of Jiangxi most concentrated, the size of mine, hundreds of down Mountain, West Mountain, Kui, Pangushan are renowned for tungsten mines.

China's the smelt tungsten mineral raw materials with foreign foreign long-term development of tungsten ore is scheelite, 60% of the total production capacity. In China, scheelite has proved reserves of 3.76 million tons, accounting for 71% of the total reserves of tungsten ore, but due to some large, very large deposits of tungsten ore material composition is complex, disseminated fine grain size, smelt not yet completely resolved, and therefore at this stage mining is still the quartz vein-type wolframite, accounting for 90% of the national recovery of ore.

Use
Tungsten concentrates is the production of tungsten iron, sodium tungstate, ammonium paratungstate (APT), the main raw material of the tungsten compounds of ammonium metatungstate (AMT), its downstream products of tungsten trioxide, blue tungsten oxide, tungsten powder, tungsten carbide, tungsten carbide, tungsten carbide, tungsten, tungsten, etc.
