Tungsten is a non-ferrous metal and an important strategic metal. Tungsten ore was called "heavy stone" in ancient times. In 1781, the Swedish chemist Carl Wilhelm Scheele discovered scheelite and extracted a new element acid-tungstic acid. In 1783, it was discovered by the Spanish Depuria that wolframite also extracted tungstic acid.

Tunsten Ores and Concentrates | Buffalo Tungsten

Tungsten Concentrates. The ore is concentrated at the mine site until it reaches 65% tungsten oxide (WO 3) content. Tungsten has a high density so gravity methods separate it from the waste rock. After crushing the ore it passes over shaker tables with water and the lower density materials are the tailings.
