The mineral form of calcium fluoride, a halide mineral that crystallizes in isometric cubic habit and defines value 4 on the Mohs hardness scale. Also called fluorspar, it gave its name to the element fluorine and to the property of fluorescence.

In Discipline: Economic Geology, Uses section
Metallurgical grade fluorite (60-85% CaF2), the lowest of the three grades, has traditionally been used as a flux to lower the melting point of raw materials in steel production to aid the removal of impurities.
