Hydrometallurgical Copper Extraction Process

The successful development of the Cyprus Copper Process has been an evolutionary series of events covering a time span of some seven years. What does the Cyprus Copper Process do? Very simply, it converts copper concentrates of varying composition into copper metal which has been proven to be equivalent in every way to electrolytic tough pitch copper suitable for electrical applications. This ...

Especially for copper and cobalt, solvent extractions are already established unit operations. For the extraction of copper, oximes are the most common extractants. For the extraction of cobalt from sulfate solutions, phosphonic acids are used. In this work, the usage of solvent extraction for copper and cobalt is investigated. 10, 16, 17

Hydrometallurgical Extraction of Zinc and Copper — A

The most commonly used route in the hydrometallurgical extraction of zinc and copper from a sulphide ore is the concentrate-roast-leach-electro winning process. In the present investigation a zinc-copper ore from the Maranda mine, located in the Murchison Greenstone Belt, South Africa, containing sphalerite (ZnS) and chalcopyrite (CuFeS 2 ), was studied.

Solvometallurgical process for extraction of copper

Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).
