In the St. Lawrence area, the veins are persistent for great lengths and several of them have wide lenses. 5. It is associated with quartz and leafy aggregates of baryte. Perhaps fluorines most potent threat though, comes from its use in compounds that can be handled with little to no risk. In these rocks it often occurs as a gangue mineral associated with metallic ores. Apatite occurs in three main varieties and the one that naturally makes up the enamel layer of our teeth is called hydroxyapatite. Pure fluorite is colourless and transparent, both in visible and ultraviolet light, but impurities usually make it a colorful mineral and the stone has ornamental and lapidary uses. Vein mining is commonly done by shrinkage stoping, cut-and-fill, and open stoping where strong walls occur. Sometimes in order to increase the inhibitory effect of sodium silicate on quartz, some multivalent metal ions will be added. Color zoning or banding is commonly present.

The best way to learn about minerals is to study with a collection of small specimens that you can handle, examine, and observe their properties. Fluorite is an important industrial mineral composed of calcium and fluorine (CaF2). EC 232-188-7. they contain diamonds that were formed at the high temperature and pressure fluorite, 4, 315 wear-resistant parts, and other technology products are now synthetic. Industrially, fluorite is used as a flux for smelting, and in the production of certain glasses and enamels. [37] Naturally occurring fluorite crystals without optical defects were only large enough to produce microscope objectives. Its crystals are usually made up of different planes that all meet at 90 angles. It is also found in some greisens, granites, pegmatites and high-temperature veins, and as a component of some marbles and other metamorphic rocks. consumer glass objects more attractive or more durable. product that contain the mineral of fluorite. Fluorite is deposited in veins by hydrothermal processes.
