Fluorite and calcite, two mineral types, are vastly different in shape and behavior. For example, fluorite grows using a symmetrical crystal system, while calcite forms asymmetrically. Calcite is considered a common mineral, while fluorite is a semiprecious mineral.
It is also used as a flux substance. It is most commonly occurring in Europe, America, Asia, Africa, with Mexico and China being the top producers. It is the gem of the state of Illinois. Since the early 19th century, fluorite was mined heavily in this state. But there is no such mining
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 openhearth steel and steel enamelware production, the smelting of aluminum, as well as lead and antimony
Fluorite is the only mineral for which significant quantities of the important element fluorine can be obtained. Fluorite is also used as a flux in the manufacture of steel and other metals to eliminate impurities.There is a great demand for Fluorite in the optics field, and to meet it synthetic crystals are grown to produce special lenses.
The openhearth steel furnace process, which was introduced in the 1880s, used fluorite for flux, increased demand considerably, and largescale mining for fluorite began in Illinois soon after. In 1890 the Fairview Mining Company began mining fluorite, and in 1893, the property was purchased by the Rosiclare Lead Fluorspar Mining Company.
