Copper Miningand Processing: Processing ofCopper.Copperprocessing is a complicatedprocessthat begins withminingof the ore (less than 1%copper) and ends with sheets of 99.99% purecoppercalled cathodes, which will ultimately be made into products for everyday use.The most common types of ore,copperoxide andcoppersulfide, undergo two different processes, hydrometallurgy and ...
Copperis usually found in nature in association with sulfur. Purecoppermetal is generally produced from a multistageprocess, beginning with theminingand concentrating of low-grade ores containingcoppersulfide minerals, and followed by smelting and electrolytic refining to produce a purecoppercathode.
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of theCopper MiningandCopperExtractionProcess. Starting from either open-pit or undergroundminingand using a different relevant treatment method for oxide or sulphidecoppermineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted. There are two main ...
Inrefining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than hascopper.In these operations some of thecopperis oxidized to cuprous oxide and dissolved by the metal bath.
