Tungsten Ore

Article body
Tungsten ore is a rock from which the element tungsten can be economically extracted. The ore minerals of tungsten include wolframite, scheelite, and ferberite (an Fe-rich endmember of a solution series with hubnerite, a Mg-rich tungsten oxide). Tungsten is used for making many alloys.

Tungsten ore deposits are predominantly magmatic or hydrothermal in origin and are associated with felsic igneous intrusions. Such deposits include but are not limited to veining and stockwork, disseminated or greisen, skarns, stratabound, or porphyry deposits. It is often associated with cassiterite in granitoid type stockwork systems, such as the Pilok tin-tungsten deposit at the border of Burma and Thailand.

Currently, the largest producer and consumer of tungsten bearing ore is China. China also has the largest reserves at nearly 60% of global output in 2019.
