The amount of tungsten in Earth’s crust is estimated to be 1.5 parts per million, or about 1.5 grams per ton of rock. China is the dominant producer of tungsten; in 2016 it produced over 80 percent of total tungsten mined, and it contained nearly two-thirds of the world’s reserves. Vietnam, Russia, Canada, and Bolivia produce most of the remainder. Tungsten does not occur as a free metal. It is about as abundant as tin or as molybdenum, which it resembles, and half as plentiful as uranium.
The mining of tungsten and other metal minerals has obvious damage to the surrounding environment. Therefore, the environmental protection cost in the process of tungsten mining is higher and higher, and the environmental restoration is more and more difficult.
