China Flotation Or Leaching Sx Ew Process Copper Plant

Nov 08, 2015 Copper was extracted on asphalt-lined leach pads and recovered in the first solvent extraction and electrowinning (SX/EW) plant in Latin America. Production capacity was 33,000 metric tonnes per year (mtpy) of high purity copper cathodes. At the time, the use of solvent extraction followed by electrowinning for low grade, impure leach solutions

Jun 15, 2018 A new flotation tailings treatment process was developed for efficient Cu recovery. • An efficient Cu dissolution was achieved in an H 2 O media in presence of pyrite.. The dissolution mechanism of CuFeS 2 has been confirmed to be a multistage reaction.. Fe was always co-dissolved with Cu following a linear relation of C Fe = 38.393 C Cu.. Over 91% Cu was extracted from pregnant leach

Sep 01, 2002 Traditional copper processing is termed pyrometallurgy as it involves high temperature smelting. In contrast, SX-EW is a hydrometallurgical process involving the dissolution and reprecipitation of copper from solution. There are three fundamental steps to SX-EW: ore leaching, solvent extraction, and electrowinning
