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.
