<p><P>PROBLEM TO BE SOLVED: To provide a method of preventing short-circuit trouble in a metal electrowinning having a risk that the short circuit trouble occurs because a non-conductive material is locally deposited on a part of an anode in the stoppage of energizing to produce dendrite due to the concentration of current onto a part where the non-conductive material is not deposited in the re-start of the energizing. <P>SOLUTION: In the deposition and the winning of the metal on a cathode 13 by dipping the anode 12 and a cathode 13 into an electrolyte 15 in which metallic ion is dissolved and energizing, an anodic material 14 is applied only on the anode surface positioned under the liquid level 16a of the electrolyte 15 in the dipping only the anode 12 into the electrolyte 15. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
