1 The Fluorspar Beneficiation Problem. Acid grade fluorspar which is in great demand by the chemical and aluminum industries, must contain at least 97.5% CaF 2 with not more than 1.5% SiO 2 and 0.5% Fe 2 O 3. Often the Silica is limited to 1.2% with penalties starting at 1.0% SiO 2. These limitations on grade and impurities require extremely close mill control, particularly through flotation where selectivity and
