Why Do Copper Plants Still Choose Pb-Sb Anodes?
1. What Is a Pb-Sb Anode? A Pb-Sb anode is an insoluble lead-based anode containing 6–10% antimony (Sb), with the remainder being high-purity lead (≥99.994%). The addition of antimony significantly increases the mechanical strength and hardness of pure lead, transforming it into a rigid, wear-resistant material suitable for aggressive electrowinning environments. Some manufacturers also add […]
