  • Extraction of Tungsten from Scheelite Ore

    Scheelite is quite readily floatable with fatty acids in an alkaline circuit with soda ash and sodium silicate. Other non metallic minerals such as calcite and fluorspar are often present in the ore so a high grade scheelite concentrate is difficult to produce by flotation. Sulphides if present must be floated ahead of the scheelite. Conclusion
