Jun 22, 2012· Fluorspar is a halide mineral composed of calcium fluoride and is derived from the Latin root "fluo" (meaning "to flow") because the mineral was discovered to decrease the viscosity of slag in iron smelting. In 1852, fluorite gave its name to the phenomenon of fluorescence.

Fluorite Group. Fluorite is found as a common gangue mineral in hydrothermal veins, especially those containing lead and zinc minerals. It is also found in some greisens, granites, pegmatites and high-temperature veins, and as a component of some marbles and other metamorphic rocks.

Fluorine is obtained mainly from the mineral fluorite or fluorspar (calcium fluoride). Other fluorine-bearing minerals include apatite and cryolite. It is mined .

Sep 13, 2019· The vein contains the minerals sphalerite, barite, gypsum, fluorite, calcite, pyrite, and chalcopyrite (Anderson and others, 1982; Anderson, 1994). Sphalerite from the vein has been mined sporadically since its discovery, but its exploitation has been dictated by normal limestone mining .

Fluorite Mines. Fluorite (CaF 2) or fluorspar is a halide mineral composed of calcium and fluor. It is found in various different colours including colorless, white, purple, blue, green, yellow, orange, red, pink, brown, and bluish black. Actually it has been been dubbed the most colorful mineral in the world.

Fluorite was produced for the steel and glassware industries from two deposits within 1 km of Plumbago homestead, 40 km north of Manna Hill. Over 580 t were mined during 1932–36, and 110 t in 1956–58. Veins within metasediments of the Willyama Supergroup are up to 1 m wide and consist of quartz and purple fluorite.

Fluorite is the only mineral for which significant quantities of the important element fluorine can be obtained. Fluorite is also used as a flux in the manufacture of steel and other metals to eliminate impurities.There is a great demand for Fluorite in the optics field, and to meet it synthetic crystals are grown to produce special lenses.

Fluorescence in fluorite is thought to be caused when trace amounts of yttrium, europium, samarium, or other elements substitute for calcium in the fluorite mineral structure. Fluorite crystal mass: An impressive cluster of fluorite crystals from the Berbes Mine, Ribadesella, Asturias, Spain.
