extraction of tungsten from its ore

Questions and Answers How do you separate tungsten from How do you separate tungsten from its ore? Wolframite (iron-manganese tungstate, FeWO 4 and MnWO 4) and scheelite (calcium tungstate, CaWO 4) are tungsten's primary ores. The ores are ground into small particles, cleaned and then treated with alkalis to form tungsten trioxide (WO 3).The tungsten trioxide is then heated with either carbon or hydrogen gas to form the pure metal.
