The traditional anode plates used for electrowinning zinc include: Pb-Ag, Pb-Ag-Ca, Pb-Ag-Ca-Sr. Pb-Ag-Ca-Sr-RE alloy anodes. In recent years, Pb-Ag-Ca ternary alloy anode, Pb-Ag-Ca-Sr quaternary alloy anode and Pb-Ag-Ca-Sr-RE multi-component alloy anode have been used by more and more manufacturers. These three kinds of anodes have the advantages of high strength, low cost and good comprehensive performance. Our company is the first domestic manufacturer that can produce 2.6 ~ 3.6m2 large anode plates.
