ELECTROWINNING ANODE AND METHOD OF MANUFACTURE Abstract of the Disclosure A lead anode for electrowinning metals from sulfuric acid solutions is formed by soldering a sheet of lead anode material endwise in a slot, which extends longitudinally along and partially through a lead alloy coated copper bus bar and into which the sheet fits tightly, and thereafter depositing lead alloy filler at all joints between the bar and anode. Anodes thus constructed have a uniform, smooth joint between the bar and sheet and thus are corrosion resistant and exhibit uniform conductivity.
