Fluorite,
also called fluor, fluorspar is a mineral often fluorescent in
ultraviolet light. Massive fluorite may resemble calcite, but it is
heavier and does not effervesce when treated with hydrochloric acid.
It is distinguished from gypsum and quartz by its hardness. 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.
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. Such as in glasses and enamels.
It is used in hydrofluoric acid, enamel and glass industries,
refrigerating fluids, portland cement, insecticides and to retard
tooth decay. Fluorite is also used as a source of fluorine for
hydrofluoric acid and fluorinated water.
