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
Copper Ore Processing Methods
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
Evaluation of Mining Methods for Thick Tabular Ore Deposits
Tabular ore deposits form a major portion of the reserves of the coal, potash, trona, and limestone that are mined by underground methods, while some copper and lead zinc deposits are also tabular in shape. Oil shale mining represents a new addition to this group.

The Copper Country is highly unusual among copper mining districts, because copper is predominantly found in the form of pure copper metal (native copper) rather than the copper oxides or copper sulfides that form the main copper ore at almost every other copper mining district.
Copper mining. From ore to copper. SchoolScience.co.uk
The ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. The copper is recovered by electrolytic refining. Advantages of this process are much less energy is use than in traditional mining no waste gases are given off
