Numerous uses in the metallurgical, ceramics, and chemical industries. Fluorite also gave the name to its constitutive element fluorine. Fluorite is deposited in veins by hydrothermal processes. It is most often found as a pore-filling void or vein deposit, so the fluorite crystals tend to occur as a distinct layer or series of layers lining the walls of what was originally a void in the rock. Perfect cleavage in four directions to produce octahedrons, brittle. Most of the richest fluorite deposits have now been mined out, but some fluorite can still be found, especially in Illinois Hardin and Pope Counties. The fluorescence of fluorite may be due to mineral impurities, such as yttrium and ytterbium, or organic matter, such as volatile hydrocarbons in the crystal lattice. exceeds metallurgical grade. Industrially, fluorite is used as a flux for smelting, and in the production of certain glasses and enamels. Ceramic grade fluorspar is 85 - 96% pure. Fluorite has a high energy vibration that can connect one to the spiritual realms. In bedded deposits, room-and-pillar patterns are used, with the widths of rooms governed by roof conditions. If we delegate the authority, we multiply it by two. Misidentifications may also arise due to the wide range of colors that fluorite can exhibit. Fluorite is also found in the fractures and vugs of some limestones and dolomites.
