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.

In the United States, fluorite is mainly found in Kentucky, Illinois, Missouri, and Colorado. Also, it is interesting to note that fluorite is actually considered Illinois' state mineral, and it has been mined in Southeastern Illinois since the early 1800s. It is a fluorspar-rich region and is called Illinois-Kentucky Fluorspar Mining District.
