Extraction of Tungsten from Scheelite Ore - Mineral Processing & Metallurgy
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
