Wusha mine is also called tungsten concentrate. Usha can be mixed with tantalum, lead, chromium and diamond alloys to make various cemented carbides. Wusha can also be used to manufacture drill bits, metal cutting tools, potassium-piercing projectiles, engine engines, satellites and some parts of spacecraft for underground drilling and mining, as well as parts and materials with high wear resistance.
Tungsten is a rare element, including tungsten iron concentrate and calcium tungstate concentrate, and its content in the crust is only 0.8%. China's tungsten reserves account for about 55% of the world's total reserves, ranking first. Tungsten concentrates are found in North China, Northwest China and Southwest China, especially in Guangxi, Hunan, Guangdong and Jiangxi in the west and Nanling Mountains in Fujian in the east.
Brief introduction of tungsten concentrate
Among them, the tungsten mines in southern Jiangxi are the most concentrated, with hundreds of large and small mines. Dajishan, Xihuashan, Maomeishan and Pangushan are all world-famous tungsten mines. The raw materials of tungsten ore in China are different from those abroad. Tungsten ore developed for a long time abroad, mainly scheelite, accounts for 60% of the total production capacity.
The proven reserves of scheelite in China are 3.76 million, accounting for 7 1% of the total tungsten reserves in China. However, due to the complex ore composition and fine disseminated particle size of some large and super-large tungsten polymetallic deposits, the beneficiation and metallurgy technology has not been completely solved, so at this stage, Yingshi vein tungsten ore is still the main mine, accounting for 90% of the total mined ore in China.
