TUNGSTEN 18 Tungsten T ungsten is a vital metal of strategic importance. The chief sources of tungsten are minerals scheelite (CaWO 4) and wolframite [(Fe,Mn)WO 4] which are deposited by hydrothermal solutions. Tungsten has a melting point of 3,350 0C, the highest of all metals and it is resistant to all acids at ordinary temperatures. It
Industrial practice has shown that a tungsten recovery higher than 98% for sheelite concentrate and 99% for scheelitewolframite mixed concentrate is obtained, under the conditions of NaOH/WO 3 mole ratio of –, 160–170 °C, and it is suitable to treat almost any sort of tungsten ore concentrates, including low grade complex concentrate, and it is more effective than the traditional soda ash digestion process.
