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 ...
Leaching offers an alternative tocopper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolvingcopperto form a weak solution ofcopper sulphate. Thecopperis then recovered by electrolysis.
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.
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.
The shaft was created in 1971 for a previousminingoperation on the site and now is being rehabilitated and deepened to 6,800 ft., aprocessthat will take two more years.

Coppercan be found underground in the form ofcopperore. The maincopperore producing countries are Chile, theUnited States, Indonesia, Australia, Peru, Russia, Canada, China, Poland, Kazakhstan, Zambia, Zaire and Mexico. What HasCopperBeen Used for in the Past?Copperwas one of the first metals used by humans.
