Sphalerite, however, has other appearances. In fact, the name sphalerite is from the Greek sphaleros which means deceiving or treacherous. This name refers to the many different appearances that sphalerite may have.About Sphalerite Group Hide. The diamond structure has two interpenetrating cubic close packed carbon lattices. Each atom of theses lattices is tetrahedrally coordinated by 4 atoms of the other lattice. If one of these lattices is replaced by cations (A) and the other replaced by anions (X), where X = S, Se, Te we get the sphalerite group.Sphalerite is a sulfide mineral with the chemical formula S. 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.

Feb 1, 2022 · Sphalerite, the dominant ore-mineral of Zn, is mainly composed of Zn and S, but Fe concentrations up to 15 wt% are observed due to substitution for Zn, or as inclusions (Cook et al., 2009). In addition, minor and trace elements ( e.g. , Cd, Mn, As, Ag, Cu, Co) are also hosted in sphalerite in a wide range of concentrations ( Cook et al., 2009 ). The main minerals in this deposit are sulphide minerals such as pyrite, sphalerite, chalcopyrite and galena. The term “massive sulfide” deposit refers to any deposit containing more than 50% sulfide minerals. The modifier “volcanogenic” indicates that the massive sulfides are believed to be genetically related to volcanism that was ...The other mineral that can carry significant indium in base metal ores is chalcopyrite (e.g., Gaspar, 2002). Concentrations of indium are, however, lower than in co-existing sphalerite (e.g., Cook et al., 2011) where the two minerals co-exist, suggesting a strong fractionation into the zinc sulphide. Chalcopyrite can potentially account for a ...

The highest In content in sphalerite is characteristic of chalcopyrite-free ore-bearing mineral assemblages. The sphalerite-chalcopyrite association is, however, typical of the proper indium mineral, roquesite. Sphalerite in this association is distinguished by a low indium content (260–657 ppm).Pyrrhotite הוא מינרל חשמלי שנוצר בטמפרטורות גבוהות ומשתנה בהתאם ללחץ ולהרכב הכימי. הוא נמצא בצבעים של אור הלהבה, מאדום-חום עד שחור. באתר mindat.org תוכלו למצוא מידע על המאפיינים, המיקומים והתמונות של המינרל המעניין הזה.
