ANODE A LONGUE VIE POUR L'EXTRACTION ELECTROLYTIQUE

A LONG LIFE LEAD ANODE FOR ELECTROWINNING ABSTRACT An anode for electrowinning in an aqueous sulfuricacid-containing electrolytic cell. A plate member has a lead or leadalloy outer surface. The outer surface is rough and containselevations and depressions. Lead sulfate oxidized from the roughouter surface of the lead plate member to adhere to the elevationsand depressions of the rough outer surface for reducing flaking oflead sulfate. A support means suspends the lead plate member in theelectrolyte.
