  • Extraction of Tungsten from Scheelite Ore

    A marketable grade of scheelite is rarely, if ever, made by flotation, but an increased recovery is realized by its use and the product can be treated by soda ash solution in an autoclave. In this process the scheelite is dissolved and, by addition of lime, calcium tungsten, or synthetic scheelite, is precipitated. Reagent Combinations
