Large Copper Oxide Ore Separating Metals

For copper oxide ore electrowinning is the final stage in the process of hydrometallurgy in which concentrated copper solution from the heap leaching and solvent extraction processes is used as an electrolyte an electric current is applied through an inert anode resulting in the plating of copper onto 999 pure copper cathodes.
