Fluorite is commercially named fluorspar composed of calcium fluoride (CaF2). It is the principal source of fluorine. The same is used in production of hydrofluoric acid, which is used in a wide variety of industrial applications including glass etching. Fluorite tends to occur in well-formed isometric crystals, forming cubes and octahedrons.

The most commonly used beneficiation process is froth flotation, producing fluorite concentrates of up to 99% purity. Typically, fatty acid is used as collector in fluorite flotation, and water glass as a depressant of silicate gangues; the ore pulps are heated to 35–85 °C in the system ( Crozier, 1992 ).
