Copper processingis a complicatedprocessthat begins with mining of theore(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 ofore,copper oxideandcoppersulfide, undergo two differentprocesses, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of theore.

The froth is skimmed off the surface and theenriched ore(mainly thecopper mineral) is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled. After this stage theenriched orenow contains about 25%copperby mass and is calledcopper concentrate.

First, theoreis treated with dilute sulphuric acid. This trickles slowly down through theore, over a period of months, dissolving copper to form a weak solution ofcopper sulphate. Thecopperis then recovered by electrolysis. Thisprocessis known as SX-EW (solvent extraction/electrowinning).

Once the waste materials have been physically removed from theore, the remainingcopper concentratemust undergo several chemical reactions to remove the iron and sulfur. Thisprocessis called smelting and traditionally involves two furnaces as described below. Some modern plants utilize a single furnace, which combines both operations.

The proposed process aims to introduce several advantages in treating gold-copper ores and concentrates, such as (1) low cyanide consumption compared to the conventional cyanidation; (2) high gold, silver and copper extraction; (3) leaching conducted at a very low or no free cyanide in the leach solutions; (4) most of the copper in the final leach solution present as cupric glycinate; and (5) …
