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 chemical reducing agent to decompose the ore driving off other elements as gases or slag and leaving the metal base behind
