What You Should Know About Metallurgical Coal

Metallurgical coal differs from thermal coal which is 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 and contains more carbon and less moisture and ash
