The copper mining process - KAZ Minerals

The blister copper is transferred into a refining furnace. Air is blown into the molten copper to oxidise part of the copper and most of the impurities. The operator tests samples to determine when the impurities have reached the acceptable level. Oxidised copper is reduced using fuel oil to produce 99.5% pure copper. This is poured into moulds to form large plates of copper called 'anodes'.

How copper is made - material, used, processing, steps ...

The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased. Some of these steps are conducted at the mine site itself, while others may be conducted at separate facilities.
