摘要： A method for recovering metals from waste materials includes steps of contacting a waste material feed stream with a first lixiviant adapted to leach copper and other base metals from the waste material feed stream and provide a treated waste material feed stream, recovering copper metal from the first lixiviant, contacting the treated waste material stream with a second lixiviant adapted to leach noble metals from the treated waste material feed stream and recovering gold from the second lixiviant.
