Introduction to Tungsten

2021-1-19  Tungsten,(w) The main ore of tungsten is wolframite (Fe,Mn)WO4; scheelite (CaWO4) and solzite (PbWO4) are also important. The concentrated ores are fused with NaOH and, after water extraction, WO 3 is precipitated with acid and reduced to the metal with H 2 .

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.
