Abstract
In a metal-winning method, copper ore or copper-ore concentrates is effectively hydraulically leached in a chloride leach liquor and the resultant leached liquor is diaphragm-electrolyzed. A chloride electrolyte containing Br− ions and the leached metals is subjected to a diaphragm-electrolysis in an electrolytic cell comprising an anode compartment (4) and a cathode compartment (3). A portion of the electrolyte in the anode compartment (4) is withdrawn from below an anode (2) of the anode compartment (4) and is returned to the leaching step so as to increase the oxidation potential of the chloride leach liquor.
