    摘要: 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 A portion of the electrolyte in the anode compartment (4) is withdrawn from below an anode (2) of the anode compartment (4) and is returned to the leaching step so as to increase the oxidation potential of the chloride leach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.

    摘要: In a method for recovering antimony from the electrolyte of copper electro-refining process, the antimony is adsorbed on the chelating resin and is then eluted by acid. The eluate is then neutralized to recover antimony. In a conventional method, a large amount of acid and alkali is used. In the inventive eluting method, the antimony concentration in the acidic eluting solution is adjusted to 4 g/L or more in the first step and 3 g/L or less in the second step.
