Fluorspar Beneficiation Process Plant
Acid grade fluorspar which is in great demand by the chemical and aluminumindustries, must contain at least 97.5% CaF2 with not more than 1.5% SiO2 and 0.5% Fe2O3. Often the Silica is limited to 1.2% with penalties starting at 1.0% SiO2. These limitations on grade and impurities require extremely close mil…
