Flotation Plant For Copper Recovery From Bangladesh

Development of copper recovery process from flotation

Development of copper recovery process from flotation

Jun 15, 2018 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
