Solvometallurgical process for extraction of copper from

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.

Copper Mining and Production Processes Explained

Copper Mining and Production Processes Explained

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW solvent extractionelectrowinning.
