Volcanogenic massive sulfide ore deposit
Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copperzinc which are associated with and created by volcanicassociated hydrothermal events in submarine environments.. These deposits are also sometimes called volcanichosted massive sulfide (VHMS) deposits. The density generally is 4500 kg/m 3.

Crushing, a form of comminution, one of the unit operations of mineral processing. In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores .
Sulfide
Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to chemical compounds large families of inorganic and organic compounds, lead sulfide and dimethyl sulfide. Hydrogen sulfide (H 2 S) and bisulfide (SH −) are the conjugate ...

8 M3TC Report GOLD EXTRACTION AND RECOVERY PROCESSES With many sulfide ores, the ore cannot practically be ground down fine enough to expose the gold particles. For cyanide to leach gold, the cyanide solution must come into direct contact with gold molecules. The objective of pretreatment (by roasting) for these ores is to remove enough of the sulfide so that at least a small portion of all ...

Sulfide Ore
For sulfide ore processing, nickel has to be separated from the iron present in the sulfide concentrate. This is conventionally done in both the smelting and converting stages. To aid iron rejection in the smelting stage, the concentrate is first partially roasted to oxidize the iron sulfide. This is done either in a multiple hearth roaster or in a fluidbed roaster. During partial roasting in ...
Sulfide Ore
In Pergamon Materials Series, 1998. Matteslaggas reactions in CuFeNi sulphide ores. Sulphide ores are a major source of Cu, Ni and precious metals. A basic principle of the extraction processes is to blow air into the molten sulphide in order to oxidise (1) S, which forms a gas and (2) Fe, which forms predominantly FeO and then partitions to a slag phase which covers the matte.
Gold Recovery 101
Gold ore is considered freemilling when over 90% of the gold can be recovered by a conventional gravitycyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm. Some examples of freemilling gold ores include quartzveined deposits and oxidized ores. SulfideAssociated Gold Gold often occurs in close association with sulfide minerals such as arsenopyrite ...

The resultant slurry from the leaching process comprises of a solution pregnant in the metal salt and a barren ore. The first purifiion step taken after leaching is to wash the pregnant liquor solution (PLS) from the depleted ore.
