Plants for the production of lead are generally referred to as lead smelters. Primary lead production [ clarification needed ] 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 oxidizing elements 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 provided by carbon monoxide in an air-starved furnace pulls the final oxygen atoms from the raw metal.
