pyrometallurgy | Britannica

pyrometallurgy, extraction and purification of metals by processes involving the application of heat. The most important operations are roasting, smelting, and refining. Roasting, or heating in air without fusion, transforms sulfide ores into oxides, the sulfur escaping as sulfur dioxide, a gas. Smelting (q.v.) is the process used in blast furnaces to reduce iron ores.
