Lead and Zinc Smelting

for zinc manufacturing, the ore is leached with sulfuric acid to extract the lead/zinc. These pro-cesses can operate at atmospheric pressure or as pressure leach circuits. Lead/zinc is recovered from solution by electrowinning, a process simi-lar to electrolytic refining. The process most com-monly used for low-grade deposits is heap leaching.
