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 thatbine with those oxidizingelements to free the metal. Reduction is the final, high temperature step in smelting. It is here that the oxidees the elemental metal. A reducing environment often p

Smelting

OverviewProcessHistoryBase metalsEnvironmental impactsSee alsoBibliography

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent topose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agentmonly a source of carbon, such as cokeor, in earlier times, charcoal.
