    Aug 01, 2004 HydroCopper technology comprises a chloride-leaching method for copper sulfide concentrates and copper production up to semi-products. As compared with the commonly used sulfate solutions, brine solutions offer aggressiveness and stability of the copperI ion and, consequently, a lower energy consumption in leaching. CopperII ions and oxygen are used as oxidants.
