What You Should Know About Metallurgical Coal

Aug 21, 2020· Metallurgical coal differs from thermal coal, used for energy and heating, by its carbon content and its caking ability. Caking refers to the coal's ability to be converted into coke, a pure form of carbon that can be used in basic oxygen furnaces. Bituminous coal—generally classified as a metallurgical grade—is harder and blacker.
