Popis: In the past 25 years, the recovery of copper by leach/SX/EW techniques has matured as a technology. It has developed from an operation of secondary importance which treated old waste dump materials to produce a finished cathode of inferior quality to that of conventional electrorefineries into one of the bright stars of the future of the copper industry. Plants now process ore that is “mined for leach” in highly efficient plants to produce premium quality electrolytic cathodes at operating costs as low as $0.35/lb.
