Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative, Mississippi-Valley type, and volcanogenic massive sulfide deposits. It is found in association with galena, chalcopyrite, pyrite , calcite, dolomite, quartz, rhodochrosite, and fluorite.Sphalerite (sometimes spelled sphaelerite) is a sulfide mineral with the chemical formula ( Zn, Fe) S. [5] It is the most important ore of zinc. Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative, Mississippi-Valley type, and volcanogenic massive sulfide deposits.

Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment.A former New Jersey Zinc Co. zinc property mined principally for hemimorphite-rich ore.
