Copper Mining and Processing: Resources and Glossary

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 99.9% pure copper cathodes.

Copper Production: How Is Copper Made? ThoughtCo

Sep 26, 2019 Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.
