Solvometallurgical process for extraction of copper from

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).

Electrolytic production of copper from chalcopyrite

Aug 01, 2020· Another approach is to simply accept the slow copper extraction rates and use chalcopyrite primarily for energy storage. Deen and Asselin demonstrate a fixed bed flow cell, where the Fe 2+ /Fe 3+ redox reaction in the presence of Cu is the charge/discharge process. Coulombic efficiency decreased by ∼20% (from 80% initially) over 400 cycles.

Why the Extraction of Copper from Chalcopyrite is so

About 3/4 th of Copper (Cu) produced in the world has come from Chalcopyrite (CuFeS 2), but it is the lowest standard ore of Copper. The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores.

Chalcopyrite Leaching

Leaching Chalcopyrite is the holy grail for hydrometallurgists (Leachers), difficult to leach as the sulfur forms a layer over the mineral and makes the leaching slow. Having said that, it is not 100% not leachable, not unusual for ore dumps (low grade) containing chalcopyrite to be placed under leach but report low recovery +/-30% TCu over several years and the rate is around 0.5-1% per month
