This KS3 education resource looks at copper mining, extraction and pyroprocessing of sulfide ores. This KS3 education resource looks at copper mining, extraction and pyroprocessing of sulfide ores. These processes created the Andes mountain chain that you can see behind the picture of El Teniente (below). Millions of years of volcanism and
In the former process, the copper is stored in the organic phase as a complex of the ion exchange reagent. For example, in selective extraction of copper with LIX 64N, the LIX will react with copper to form a hydrophobic copper complex which will preferentially remain in the oil phase.
The copper is recovered by electrolytic refining. Advantages of this process are much less energy is use than in traditional mining no waste gases are given off it can be used on ores with as little as 0.1% copper for this reason, leaching extraction is growing in importance.

Copper can be extracted from non sulfide ores by a different process involving three separate stages Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution. Concentration of the copper(II) sulfate solution by solvent extraction.
Copper recovery using leach/solvent extraction/electrowinning technology Forty years of innovation, 2.2 million tonnes of copper annually by G.A. Kordosky* Synopsis The concept of selectively extracting copper from a low grade dump leach solution followed by stripping the copper into an acid solution from which electrowon copper cathodes could
Nov 06, 20180183;32;Aug 2, 2011 lurgical testing indicates copper extraction will vary by ore type and, if controls are not implemented, may lead been renewed interest in the process recently, due to acidification recycle thickening (SART) has been. Chemical metallurgical extraction processes are usually dewatering by thickening and filtering).
