What You Should Know About Metallurgical CoalASTM D388 19a Standard Classification of Coals by Rank

Jul 15 32 Metallurgical coal also known as coking coal is used to produce coke the primary source of carbon used in steelmakingCoal is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forcNote 1 Coals rich in inertinite or liptinite exinite or both cannot be properly classified because in those macerals the properties that determine rank calorific value volatile matter and agglomerating character differ greatly from those of vitrinite in the same coal Often such coals can be recognized by megascopic examination In North America these coals are mostly nonbanded
