    Lead is mostly extracted from galena PbS which is concentrated by a froth flotation process. This concentrated ore is then roasted in a limited supply of air to give lead oxide, which is then mixed with coke and a flux such as limestone and reduced in a blast furnace: PbS + 1.5 O 2 → PbO + SO 2 PbO + C → Pb (1 iq) + CO
