Copper Mining and Processing: Processing of Copper Ores

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

A review of the beneficiation of coppercobaltbearing

Lowgrade ore deposits are of increasing interest in mineral processing owing to dwindling resources of high grade, easily exploited ores. For CuCo ores in the DRC, oxidised ore deposits have historically been the main source of CuCo as they are relatively simple to process, mainly by leaching/solvent extraction/electrowinning.

Copper oresDanafloat

When liberated, typical copper sulphide minerals are relatively easy to float. When there are no overriding metallurgical issues, producing a sufficiently high copper concentrate grade is often the focus. Often the primary grade control issue relates to iron sulphide minerals since these also float with the copper, diluting copper concentrate

Copper Mining and Extraction Sulfide Ores

Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of this process are: See for further
