Fluorite (Industrial name fluorspar) is a mineral from the group of halides, formed by the combination of calcium and fluoride, which crystallizes in the cubic system. Formula CaF2 . Fluorite , from the Latin fluere (flow), owes its name to that property.
Fluorite Group. Fluorite is found as a common gangue mineral in hydrothermal veins, especially those containing lead and zinc minerals. It is also found in some greisens, granites, pegmatites and high-temperature veins, and as a component of some marbles and other metamorphic rocks.
Another large private mining group is the CRAM or Compagnie Royale Asturienne des Mines, which largely owns the Compagnie Minière de Touissit (CMT) that mines the remaining MVT-style Zn-Pb deposits in the NE of the country.
