  • Fluorspar Extraction Processing Flowsheet

    Fluorspar is found generally in veins, in gneiss, slate, limestone, crystalline limestone, and sandstone; often as gangue of metal ores, particularly of lead ores. It is sometimes mixed with barite and celestite; and as these minerals are partly sulphur in composition, they lower the value of fluorspar, as sulphur is injurious to iron and steel.
