Fluorite (also called Fluor***r) is a halide mineral composed of calcium fluoride (CaF2). Fluorite comes in a wide range of colors and has subsequently been dubbed "the most colorful mineral in the world". The most common colors are purple, blue, green, yellow, and colorless. Less common are pink, red, white, brown, black, and nearly every shade in between. lndustrial production of fluorine in the middle temperature process entails the electrolysis of a potassium bifluoride solution in hydrogen fluoride. Hydrogen fluoride required for the electrolysis is mainly obtained by treatment of fluorite with sulfuric acid. Several thousand tons of fluorine are produced annually. Potassium bifluoride forms spontaneously from potassium fluoride and the hydrogen fluoride.
There are three principal types of industrial use for natural fluorite, corresponding to different grades of purity. Metallurgical grade fluorite (60¨C85% CaF2), the lowest of the three grades, has traditionally been used as a flux to lower the melting point of raw materials in steel production to aid in the removal of impurities, and later in the production of aluminium. Ceramic grade fluorite (85¨C95% CaF2) is used in the manufacturing of opalescent glass, enamels, and cooking utensils. The highest grade, "acid grade fluorite" (97% or more CaF2), accounts for about 95% of fluorite consumption in the US where it is used to make hydrogen fluoride and hydrofluoric acid by decomposing the fluorite with sulfuric acid.
