It's Elemental - The Element Tungsten

Tungsten ores are crushed, cleaned and treated with alkalis to form tungsten trioxide (WO 3). Tungsten trioxide is then heated with carbon or hydrogen gas (H 2), forming tungsten metal and carbon dioxide (CO 2) or tungsten metal and water vapor (H 2 O).

Extracting Tungsten from Wolframite Gold Ore

Straight gravity concentration of this ore, using the flowsheet shown, would result in a mixed gold-tungsten concentrate containing much sulphide which is not desirable for marketing. Consequently, it is evident that other concentration processes must be incorporated in the flowsheet to produce separate marketable concentrates of tungsten and gold.
