Copper Processing: The Quest for Efficiency at Scale | E & MJ
Advances in copper processing technologies from the past 30 years nearly all fall into the category of "the bigger, the better" — higher volume flotation cells, massive high-pressure grinding rolls (HPGRs), super-sized concentrators. For some time now, we have been chasing economies of scale, which will soon cease to exist. ...

Innovations: How Hydrometallurgy and the SX/EW Process Made
The SX/EW Process. The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal. Because of its dependence on sulfuric acid, the SX/EW Process is at present not a substitute for, but ...

Current Status of Copper-Ore Processing: A Review
IN PROCESSING COPPER ORES In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia [4]) owing to the exhaustion of rich copper resources. The flowsheet of processing copper ores is

Copper Processing | Multotec
Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.

The Extraction of Copper
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
