What You Should Know About Metallurgical Coal
· Bituminous coal—generally classified as a metallurgical grade—is harder and blacker. It contains more carbon and less moisture and ash than lowrank coals. The grade of coal and its caking ability is determined by the coal's rank—a measure of volatile matter and degree of metamorphism—as well as mineral impurities and the ability of the coal to melt, swell and resolidify when heated.
