Fluorite is commercially named fluorspar composed of calcium fluoride (CaF2). 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.

The invention is especially appropriate in the flotation process for an acid grade fluorspar enriched concentrate having a fluorspar content of at least about 96.5% and a sulfide sulfur content of not greater than about 0.02%, from a fluorspar ore containing, in addition to fluorspar, substantial amounts of gangue minerals and metallic sulfide ...

The average price of fluorspar in the United States reached an estimated 430 U.S. dollars per metric ton in 2023. Fluorspar, also known as fluorite, is the mineral form of calcium fluoride. It is ...

Fluorspar ore commonly contains fluorspar (CaF 2), silica, calcite, clay minerals, and, in certain instances appreciable quantitites of the mineral, apatite (Ca 5 (PO 4) 3 (F,OH)). In the production of commercial grades of ore, such as acid-grade fluorspar, it is necessary to concentrate the fluorspar and remove substantial quantities of the gangue materials.

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. Fluorite occurs most commonly as a glassy, many-hued vein mineral and is often associated with lead and silver ores; it also occurs in cavities, in ...

The fluorspar ore from these mines are processed in the Bor-Undur ore dressing plant (ODP) and produce Fluorspar acid concentrate (FF-97, FF-95) and metallurgical concentrate (FK-75) as final products.
