Roasting | metallurgy | Britannica

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. Tin, copper, and lead ores are also smelted. Read More.
