Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. Mohs scale of mineral hardness, based on scratch Hardness comparison, defines value 4 as Fluorite.
Fluorite has three main types of industrial uses depending on its grade.Metallurgical grade fluorite is used in iron and steel production. Fluorite is used as a flux to lower melting points of molten metals and remove impurities such as phosphorus and sulfur. Every ton of metal produced requires 20 to 60 pounds of fluorite. Ceramic grade fluorite is used to make ceramics and specialty glassware.
