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.

fluorite and apatite constitute common gangue minerals in scheelite ores. due to their similar surface properties and good floatability the separation of scheelite from fluorite is particularly difficult. these ores are usually processed at basic ph using sodium silicate as a gangue mineral depressant and a fatty acid as the collector.
the mohs scale of mineral hardness based on scratch hardness comparison defines value 4 as fluorite.. pure fluorite is transparent both in visible and ultraviolet light but impurities usually make it a colorful mineral and the stone has ornamental and lapidary uses. industrially fluorite is used as a flux for smelting and in the production of certain glasses and enamels.
fluorite also occurs as a gangue mineral in some base metal deposits (e.g. mississippi valley type deposits). these consist of veins or replacement bodies and cavity fillings of fluorite carbonates quartz and silver–lead– zinc mineralisation in carbonate sequences. other deposit types (for fluorine) of lesser economic
fluorite is a widely occurring mineral that occurs globally with significant deposits in over 9000 areas. it may occur as a vein deposit especially with metallic minerals where it often forms a part of the gangue (the surrounding "host-rock" in which valuable minerals occur) and may be associated with galena sphalerite barite quartz and calcite.
fluorite is deposited in veins by hydrothermal processes. in these rocks it often occurs as a gangue mineral associated with metallic ores. fluorite is also found in the fractures and cavities of some limestones and dolomites. it is a very common rock-forming mineral found in many parts of the world. in the mining industry fluorite is often
