The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a number of factors – such as the ...

The recovery of gold from aqueous solutions using the clectrolytic reactor yields a high deposition rate. Despite low initial gold levels the reactor is effective in removing metal ions from solutions especially in the form of gold alloy deposits. Final gold concentrations as low as 0.1 mg 1-~ could be obtained.
