Metallurgical ContentThe Fluorspar Beneficiation ProblemA Fluorspar Flotation Process FlowsheetCrushing Fluorspar OreGrinding Circuit The Fluorspar Beneficiation Problem Acid grade fluorspar which is in great demand by the chemical and aluminum industries, 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
Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

4. Fluorspar The mineral fluorspar consists of 51.1% calcium and 48.9% fluorine in its pure form (CaF 2). In this case, it is colorless and transparent but different colors can be induced by impurities in the crystal structure. Most fluorspar is extracted either in pure veins or in association with lead, silver, or zinc ores. Commercial
