Smelting - Wikipedia
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 stone reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
