2024年10月17日 · fluorite, common halide mineral, calcium fluoride (CaF 2), which is the principal fluorine mineral. It is usually quite pure, but as much as 20 percent yttrium or cerium may replace calcium.
U.S. fluorspar consumption was satisfied primarily by imports. Domestically, production of HF in Louisiana and Texas was by far the leading use for acid-grade fluorspar.
Fluorite - Minerals Education Coalition
Fluorite is commercially named fluorspar composed of calcium fluoride (CaF 2). 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. Fluorite tends to occur in well-formed isometric crystals, forming cubes and octahedrons.
