Development of copper recovery process from flotation tailings by a combined method of high‒pressure leaching‒solvent extraction
Abstract
A new flotation tailings treatment process was developed for efficient Cu recovery. An efficient Cu dissolution was achieved in an H2O media in presence of pyrite. The dissolution mechanism of CuFeS2 has been confirmed to be a multistage reaction. Fe was always co-dissolved with Cu following a linear relation of CFe = 38.393 × CCu. Over 91% Cu was extracted from pregnant leach solutions by LIX-84I in Kerosene.
