    Abstract: 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.

    Abstract: An improved insoluble anode for electrowinning is described which comprises a graphite substrate covered by a tight fitting sheet of a nonconductive electrolytically inert mesh material over which covered substrate is electrodeposited a layer of lead dioxide. The anode is formed by covering the graphite substrate with a sheet of the inert mesh material and thereafter electrodepositing lead dioxide thereon until a smooth layer of lead dioxide completely covers the mesh material. The anodes are electrolytically stable and are not susceptible to cracking.

    Abstract: A process for recovery of substantially all lead values in battery sludge as metallic lead is disclosed. By means of the process, lead is substantially completely and efficiently recovered as metallic lead in an environmentally acceptable manner. The process comprises (a) subjecting the sludge to low temperature reducing conditions; (b) converting lead sulfates to insoluble nonsulfur containing compounds while solubilizing all sulfur materials and thereafter separating the solid residue by solid-liquid separation techniques; (c) dissolving the solid products resulting from steps (a) and (b) in an acid selected from the group consisting of fluoboric and fluosilicic acid; (d) collecting the supernatant from step (c) by means of solid-liquid separation techniques; and (e) electrowinning the lead from the collected supernatant. The lead peroxide reduction of step (a) may be effected by low temperature reducing roasts or by contacting the lead peroxide with sulfur dioxide gas or sulfites.

    Abstract: An electrowinning anode is formed by tightly joining a sheet of lead anode material to a copper busbar using solder to fill the joint. The busbar is optimally coated with a tin alloy by dipping the busbar into the alloy prior to being joined with the sheet. A lead coating is electrodeposited onto the busbar and the soldered joint to provide a complete metallurgical seal and good resistance to acid corrosion.
