Fluoride, a naturally occurring element, exists in combination with other elements as a fluoride compound, and is found naturally in water, foods, soil, and several minerals such as fluorite and fluorapatite. Fluoride normally enters the environment and human body through water, food, industrial exposure, drugs, cosmetics, etc. However, …

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. It is the source of fluorine in the …
In Our Society: The Economic Importance of Fluorite. The name 'fluorite' comes from the Latin word 'fluere' that means "to flow.". Fluorite melts easily and is used as a flux in the smelting of metallic ores. A 'flux' is a material used to help remove impurities from ore as it is refined into metal.

The research is based on the Impacts of mining fluorspar on the physical environment at Kimwarer Area, Kerio Valley Elgeyo-Marakwet County, Kenya. Therefore this study has been carried out to establish environmental impacts of fluorite mining industry on topography and land cover.
At pHs between 4.5 and 6.5, fluorite appears to be stable. At 10 −2.5 M Ca 2+, for neutral and slightly soils acidic, fluorite will be able to hold up to 10 −3.96 M F − in the solution. Calcite reduces the solubility of Ca 2+, which then permits the equilibrium activity of F − with fluorite to rise in calcareous soils. The pH ranges ...
However, fluoride pollution in the environment occurs because the chemical is synthesized for intentional use in community water fluoridation, dental products, and other consumer items. Obviously, fluoride pollution …
