Lead Processing P2 InfoHouse

Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. The mixture is blasted with hot air to burn off the sulfur and sent to the smelter. Lead is usually smelted in a blast furnace
