ABSTRACT:
In an electrowinning anode in which a lead anode sheet is tightly fitted to a copper busbar, the anode sheet is additionally joined to the busbar by pinning to prevent damage to the joint. A lead coating is electrodeposited onto the busbar, pin and the soldered joint to provide a complete metallurgical seal and good resistance to acid corrosion.
