- beneficiation fluorspar 2000
Fluorspar ore commonly contains fluorspar (CaF 2), silica, calcite, clay minerals, and, in certain instances appreciable quantitites of the mineral, apatite (Ca 5 (PO 4) 3 (F,OH)). In the production of commercial grades of ore, such as acid-grade fluorspar, it is necessary to concentrate the fluorspar and remove substantial quantities of the gangue materials.
