Historically, fluorite mineralization in the St. Lawrence area has been associated with the granite batholith and past exploration has been directed toward areas known to be underlain by granite. The recent diamond drill program, completed during 2013, identified a significant fluorite bearing structure hosted in the meta-sediments.
Fluorspar ores may be quite complex, particularly when associated with lead and zinc sulphides, barite, calcite, iron oxide, and siliceous impurities. For this reason, a laboratory flotation test should be the first step in establishing a flowsheet.

Fluorite mining, which supplies most global fluorine, peaked in 1989 when 5.6 million metric tons of ore were extracted. Chlorofluorocarbon restrictions lowered this to 3.6 million tons in 1994; production has since been increasing.

Field Trip: Fluorite and Secondary Lead-Zinc Minerals from Marion, Kentucky. Site Description: The Illinois-Kentucky Fluorspar district is world famous for the enormous quantity of huge, gorgeously crystalline purple and yellow fluorite that originated from the now defunct mines near Cave-In-Rock Illinois.
Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF 2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 4 as Fluorite.
Fluorite is deposited in veins by hydrothermal processes. In these rocks it often occurs as a gangue mineral associated with metallic ores. Fluorite is also found in the fractures and cavities of some limestones and dolomites. It is a very common rock-forming mineral found in many parts of the world.
And when mixed with sulphuric acid, fluorite produces hydrogen fluoride, an important industrial chemical precursor. However, fluorite can be quite dangerous to both those who handle it regularly and those who simply happen to live near a flourite mine.

Most of the mining recovered the surficial residual deposits that accumulated above the vein deposits and ore deposits in the shallow subsurface; however, there is still a substantial reserve of fluorspar and zinc in additional deposits, both in underexplored surface areas and in deeper deposits.
Fluorine compounds are essential in numerous chemical and manufacturing processes. Fluorspar is the commercial name for fluorite (isometric CaF2), which is the only fluorine mineral that is mined on a large scale. Fluorspar is used directly as a fluxing material and as an additive in different manufacturing processes.
Fluorite is commercially named fluorspar composed of calcium fluoride (CaF2). It is the principal source of fluorine. The same is used in production of
