What You Should Know About Metallurgical Coal ThoughtCo

Terence Bell. Updated on August 21, 2020. Metallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in steelmaking. Coal is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forces.
