    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 Copper Smelting? (with pictures)

    May 12, 2020  Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.

    Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production). Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were treated by smelting. Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters
