Fluorine is a common element in the earth’s crust formed in minerals and rocks as fluorides. The abundance of fluorine in the crust averages about 650 ppm (parts per million) and is commonly found in basalts, gabbros, andesites, granodiorites, rhyolites and granites. Marine phosphorites contain significantly higher concentrations of fluorine, averaging more than 30,000 ppm. Fluorite (CaF2), also known as fluorspar in industry, also has important uses in metallurgy including steel production, in the manufacture of ceramics and for the production of hydrofluoric acid as a precursor for other manufactured products. Optical grade fluorite with exceptional clarity is used for lenses in optical system, while specimens with exceptional color are cut into gemstones and ornaments.
