IMPROVED ELECTROWINNING ANODE AND METHOD OF MAKING SUCH ANODE.

摘要

In an electrowinning anode in which a lead anode sheet (11) is tightly fitted to a copper busbar (12), the anode sheet is additionally joined to the busbar by pinning (17) to prevent damage to the joint. A lead coating (18) is electrodeposited onto the busbar, pin and the soldered joint to provide a complete metallurgical seal and good resistance to acid corrosion.
