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

Nov 14, 2013 Copper concentrates are either smelted and refined in house, or sold to custom smelters The concentrate may be smelted to produce blister copper for sale to a custom refinery, or the blister copper may be refined to cathode, which is then sold into the market Concentrates sales contracts are specialised and very complex

Extraction and refining Extraction, concentration and refining of PGMs require complex, costly and energy intensive processes that may take up to six months to produce refined metal from the time the first PGM bearing ore is broken in a mine 1 Chamber of Mines of South Africa, Annual Report 2012 figure does not include recycling

The beneficiation process generates high volume waste called tailings, the residue of an ore that remains after it has been milled and the desired metals have been extracted e g , with cyanide gold or sulfuric acid copper If a mining project involves the extraction of a few hundred million metric tons of mineral ore, then
