Lead smelting - Wikipedia

Plants for the production of lead are generally referred to as lead smelters. 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. Smelting uses suitable reducing substances that will combine with those oxidizingelements to free the metal. Reduction is the final, high-temperature step in smelting. It is here that the oxide becomes the elemental metal. A reducing environment (often p…Lead Smelting - Base Metal Smelting,A major and primary Lead mineral is galena (chemical formula = PbS) which comprises of 86.6% of Lead [1].
