Properties of copper ores

Feel that there are copper-rich ore bodies present at this new site. there is an abundance of water and sulfuric acid that could be used to dissolve leach the copper compounds found in the ore if this is possible. leaching can be defined as the ability of a solvent such as water or sulfuric acid to dissolve precious metals from an ore body.

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.
