The Tungsten Industry Fundamentals Analysis - Ⅰ

The global tungsten supplies include nature tungsten (76%, 66% are turned into termination

products, the other 10% are the production wastes, which are turned into renewable tungsten again) and renewable tungsten (24%). The native tungsten includes Scheelite (Difficult mining, mainly for the production of tungsten iron), Wolframite (Easy for quality tungsten mining, the raw materials for tungsten refining and tungstate manufacturing.) and the black and white mixed tungsten mine. There accounted for proportions are 69%, 22% and 9%. 

The renewable tungsten mainly includes the tungsten waste generated by the production process and the tungsten products wastes recycling.     

From the native tungsten view, China’s tungsten reserves account for more than 60% of the global resources, which have obvious advantages, but after years of over-exploitation, the resource advantages of China weakened. China 's tungsten resources are mainly distributed in Jiangxi ( mainly wolframite ) , Hunan ( mainly scheelite ) , 

Henan ( mainly the byproduct of molybdenum ore products ) and other places . From a production point of view, China has reserves of 60% but bears more than 80% of the global supply. China supply determines the global supply. In order to protect the tungsten resources reasonable, China controls supply of tungsten from two large ways, mining quota management and export quota management. Judging from the trend, the total mining showed a slight growth trend, the overall export quotas showed a downward trend. But the practical effect of the mining index is not obvious , the actual production each year are significantly beyond the mining quotas found , after analysis , it was found that over-exploited mainly concentrated in the provinces of Jiangxi, Hunan, which accounted for 97% of the over-exploitation. The mainly source of overexploitation is illegal production of quota - free enterprises.
