Fluorite | Minerals Education CoalitionFluorite 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.

Fluorspar is found generally in veins, in gneiss, slate, line, crystalline line, 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.
