A second technique is vat leaching, which also requires well leachable ores. The required grain sizes of < 1 cm are much coarser as compared to agitation leaching because in vat leaching the ore is not agitated in the leaching tanks and only coarse material warrants a good permeability. Grain sizes of < 2 mm are disadvantageous as they tend to ...

Hydrometallurgy - Wikipedia

Hydrometallurgy is a method for obtaining metals from their ores. It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials. Metal chemical processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy and molten salt electrometallurgy.
