Fluorite and Fluorspar: Mineral uses and properties

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. In the mining industry, fluorite is often ...

University of Minnesota's Mineral Pages: Fluorite

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. As such, large amounts of fluorite are extensively used in open-hearth steel and steel enamelware production, the smelting of aluminum, as well as lead and antimony refining.
