Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces. The crystals are bright when fresh but often ... It is used to prevent pyrite and sphalerite mineral depression. MBS is effective for pH regulation in the froth flotation process, where it may prevent pyrite depression. Sodium Metabisulfite is also useful in avoiding sphalerite flotation due to copper activation and the presence of Tennantite/Covellite in the ore.The ore-forming minerals are predominantly sphalerite, galena, and barite. Calcite is the most common gangue mineral. Low-pyrite content supports clean concentrate with high metal recovery of +95%. Some of the deposits are surrounded by pyrite/marcasite halo. The prospects can be defined by regional stream sediment, soil, and gossan sample ...

Sphalerite is found in a variety of mineral deposit types, including sedimentary exhalative, Mississippi-Valley Type (MVT), and volcanogenic massive sulfide deposits. Many minable deposits of sphalerite are formed when the hydrothermal activity or contact metamorphism brings hot, acidic, zinc-bearing fluids in contact with carbonate rocks. Ga mainly has a deficiency in sphalerite of skarn deposits, probably owing to Ga being incorporated into the Al-silicate minerals during the mineralizing process. Moreover, we suggest that there are two substitution mechanisms of Ge in sphalerite based on data analysis: 3Zn 2+ ↔ 2Cu + +Ge 4+ and (Zn 2+ , Fe 2+ ) ↔ Ge 4+ + (vacancy).31 may 2015 ... ... minerals tend to chemically weather to various oxide and hydroxide minerals.
