Regarding the overall reserves and annual export volume of China's tungsten resources, due to industrial policy adjustments and various new exploration statistics, various slightly different opinions have been formed.
At present, the industry agrees with the data released by the US Geological Survey in 2005: China's proven tungsten reserves of 1.8 million tons (including tungsten), accounting for 62% of the world's total reserves, the current proven basic reserves of 4.2 million tons (including world tungsten) The reserves account for about 70% of scheelite and about 30% of black tungsten ore. The proportion of China's two kinds of mineral resources is also roughly the same, but China's main mining since the development of tungsten ore is the black tungsten mine.
According to industry experts and authoritative sources, the global supply of tungsten is mainly composed of two parts, one of which is the supply of new tungsten concentrate, which accounts for 76% of the total tungsten supply; the other part comes from the waste of the final tungsten product. Accounted for 24%. According to the survey of the national tungsten industry by the China Tungsten Industry Association in 2004, China's utilization rate of waste tungsten is quite low, only 10% of the tungsten supply, while the utilization rate of waste tungsten in foreign advanced countries is generally above 30%. More than two-thirds of the waste tungsten alloys and waste hard alloys used in domestic waste tungsten are imported from abroad. Generally speaking, the cost of recycling waste tungsten is lower than that of tungsten ore smelting, but it requires large environmental protection investment and strong technical support.
