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.

Preliminary experiments were conducted to evaluate the leaching of gold copper ores/concentrate by the GCS and conventional cyanidation processes. This was done using three different gold copper sources covering gold copper concentrates, gold copper oxides and gold copper sulfides ores.
Jul 05, 20180183;32;Copper Mining and Processing Processing of Copper Ores . Copper processing is a complicated process that begins with mining of the To remove the ore, boring machinery is used to drill holes into the hard rock, a process called froth floatation is used to separate the copper
Recovery from copper cobalt sulfide concentrates. The ores are treated by a sulfatizing roast in a fluidized bed furnace to convert copper and cobalt sulfides into soluble oxides and iron into insoluble hematite. The calcine is subsequently leached with sulfuric acid from the spent copper
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.
All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting. Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market.
Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Copper is found in the earth's crust and the oceans although the amount in the latter is thought to be negligible, amounting to no more than about eight months
