Copper Mining and Processing: Processing Copper

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

Copper Mining and Processing: Resources and

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.
