extraction of tungsten from its ore

Extraction of Tungsten from Its Ore

Jan 25, 2013  Tungsten is extracted from its ores in several stages. The ore is eventually converted to tungsten(VI) oxide (WO3), which is heated with hydrogen or carbon to produce powdered tungsten. It can be used in that state or pressed into solid bars. Tungsten can also be extracted by hydrogen reduction of WF6 (WF6 + 3H2 → W + 6HF) or pyrolytic ...
