EXTRACTING METALS FROM SULFIDE ORES

That is, the process involves anodic oxidation of the sulfide, a reaction that gives electrons to the mineral; these electrons are released again by the simultaneous cathodic reduction of oxygen. Since the sulfide ore-body is conducting, the anodic and cathodic processes can occur at different places. Thus, ore-bodies, when exposed to ...
