Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, ...

1. Introduction. Volcanogenic massive sulfide (VMS) deposits are strata-bound accumulations of sulfide minerals that precipitated at or near the seafloor in spatial, temporal, and genetic association with contemporaneous volcanism and are one of the most important sources of metals (Zn, Cu, Pb, Ag, and Au) in the world (Franklin et al., …

The Cu Zn selectivity shows a strong dependence on the pre-conditioning type and flotation gases for mild steel grinding, but not for stainless steel grinding. The best Cu Zn selectivity happens for the combination of 5% oxygen pre-conditioning and air flotation after mild steel grinding. It seems that galvanic reactions after or during the ...

For treating such a new ore, bulk Cu-Pb flotation followed by Zn flotation has been recommended (Sehlotho et al., 2018). An example of a sequential Cu-Pb-Zn flowsheet is given in Fig. 14 . A first flotation stage is carried out at low pH (pH 6), in which the copper sulphide is floated while both galena and sphalerite are depressed.
