<p>PURPOSE:To recover electrolytically and efficiently a copper-component by cutting a Pb alloy strip obtd. by a continuous casting method and electrolyzing an acidic soln. of a sulfuric acid contg. copper with a Pb alloy as anode. CONSTITUTION:A Pb alloy strip obtd. by a continuous casting method is cut to an anode shape and is used as a Pb anode for electrolyzing copper with an electrolytic recovering method of copper from an acidic soln. of a sulfuric acid contg. copper. Said Pb anode is cast in a reducing atmosphere to decrease inclusion of oxygen ad is formed by cutting to have a smooth surface and a uniform thickness. Said anode has high quality and high dimensional accuracy. The anode is therefore hung exactly in the stage of electrolysis and the specified space between the electrode surface is maintained. The migration of Pb to the cathode is decreased considerably, the efficiency of electrolysis is improved and further the life of the anode is extended, thus the copper-content is efficiently recovered.</p> |
