The KGS Minerals Database contains abundant information on all of the ore deposits in the Western Kentucky Fluorspar District. History and Production. The earliest mining in the district was for lead at the Columbia Mine, Crittenden County, in 1835 (Ulrich and Smith, 1905, p. 115). From 1835 to the early 1870s, little fluorspar was mined.

The term "fluorspar" refers to crude or beneficiated material that is mined and/or milled for the mineral fluorite (calcium fluoride). Fluorite is a nonmetallic mineral, containing 51.1 percent calcium and 48.9 percent fluorine. Industry practice has established three grades of fluorspar: acid grade (containing more than 97 percent calcium ...

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. Today, fluorspar is also used in aluminium production, fire ...

Commercially available Fluorspar contains about 0.8 to 1.5% Si02 plus minor trace impurities. The product is minimally hazardous when in its delivered state combined with about 10% maximum water as a filtercake. Dust hazards exist when the product is either dried intentionally or through prolonged open storage.
