zinc processing | Britannica

Brass, an alloy of copper and zinc, was produced by the Romans as early as 200 bce by heating copper, zinc oxide (ZnO), and carbon together. The zinc formed by the reduction of its oxide was absorbed into the copper and did not appear as a separate phase. Evidence suggests that zinc was first produced in quantity in India and China.

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.
