What You Should Know About Metallurgical Coal

2020-08-21  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. It contains more carbon and less moisture and ash than
