Zinc refining Wikipedia

The New Jersey Zinc Company invented this process in 1930. The process take advantage of the relatively low boiling point of zinc (907 °C (1,665 °F)) as compared to the impurities being removed in the first "column": iron and aluminium. Therefore, in the first column the zinc is heated above its boiling point and allowed to rise to a condenser. The iron and aluminium impurities sink to the bottom in the form of a solid or liquid. There are still lead and cadmiumvapor impurit

Lead and Zinc Smelting IFC

Zinc Manufacturing. In the most common hydrometallurgical process 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.
