extraction of tungsten - chemguide

The production of the tungsten(VI) oxide from the ores is complicated, and not needed for any UK A level (or equivalent) syllabus. All we are interested in is the final reduction of the oxide to the metal. Pure tungsten can't be obtained by reducing tungsten(VI) oxide using carbon, because it reacts with carbon to make tungsten carbide. Instead, the reducing agent is hydrogen.

Tungsten Plansee

Tungsten was first found in the Ore Mountains of Central Europe in the Middle Ages during the process of tin reduction. However, at that time it was considered to be an unwanted accompanying element. The tungsten ore facilitated slag formation during the reduction of tin and consequently impaired the yield. The German name for tungsten (Wolfram = "wolf's drool") comes from it's reputation as a tin-devouring ore
