3. Bioleaching - Wikipedia

   en.wikipedia.org/wiki/Bioleaching

   Bioleaching is the extraction or liberation of metals from their ores through the use of living organisms.Bioleaching is one of several applications within biohydrometallurgy and several methods are used to treat ores or concentrates containing copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt.

4. Simultaneously extracted metals and acid-volatile sulfide

   en.wikipedia.org/wiki/Simultaneously_extracted...

   When dissolved in water, sulfide has a high affinity for numerous heavy metal ions. [5] That is, the solubility-product constants (K sp ) for the sulfides of these metals are very small, meaning they will precipitate as solids when a heavy metal ion and sulfide ion come into contact, as in Equation 2, where M 2+ is a generic metal in the +2 ...

   World-wide distribution of MVT deposits (red), clastic sediment-hosted (green), and unclassified (blue) lead-zinc deposits. Source: USGS. Carbonate-hosted lead-zinc ore deposits are important and highly valuable concentrations of lead and zinc sulfide ores hosted within carbonate (limestone, marl, dolomite) formations and which share a common genetic origin.

6. Sedimentary exhalative deposits - Wikipedia

   The fluids derived their salinity from the evaporation of seawater and may have been mixed with meteoric water and pore water squeezed out of the sediments. [8] [7] Metals such as lead, copper and zinc are found in a trace amount in clastic and magmatic rocks. Saline waters may reach temperatures higher than 200°C in deeper parts of the basin.

7. Zinc sulfide - Wikipedia

   en.wikipedia.org/wiki/Zinc_sulfide

   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.

9. Group 12 element - Wikipedia

   en.wikipedia.org/wiki/Group_12_element

   Worldwide, 95% of the zinc is mined from sulfidic ore deposits, in which sphalerite (ZnS) is nearly always mixed with the sulfides of copper, lead and iron. Zinc metal is produced using extractive metallurgy. [79] Roasting converts the zinc sulfide concentrate produced during processing to zinc oxide. [80]
