Fluorite, calcium fluoride is a major industrial mineral used as a flux in steel making as well as in the preparation of hydrofluoric acid and in the ceramics industry. Mainly used for glasses and enamels. Fluorite's vitreous, cubic crystals (isometric system) and cleavable, granular masses have a wide color range (often green, blue, or purple) and may fluoresce under ultraviolet light. Hardness is 4, specific gravity 3.0-3.3. Fluorite deposits form under a wide variety of conditions: as veins produced by hydrothermal alteration, as beds and cavities in sedimentary rocks, in hot spring deposits, and in pegmatites.
