  • Smelting - Wikipedia

    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 to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a source of carbon, such as coke—or, in earlier times, charcoal.

  • What Is a Smelting Plant? (with pictures)

    May 25, 2020  A smelting plant is an industrial location where metal is extracted for raw ore. Common examples of metal smelting include tin, lead, copper, bronze, and iron.The extraction of pure aluminum is also called smelting, although the process is significantly different from that of the other ores.
