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.

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.

Metallurgical coke is produced by destructive distillation of coal in coke ovens. Prepared coal is "coked", or heated in an oxygen-free atmosphere until all volatile components in the coal evaporate. The material remaining is called coke. Most metallurgical coke is used in iron and steel industry processes such as blast furnaces,

Metallurgical coke is widely used in various industries in Japan. In a coke furnace, coal is heated indirectly (for 14 to 18 hours at 1,200 to 1,300°C) and then carbonized (dried by distillation) for about 24 hours. Subsequently, it is fractionated into coke and other materials, such as gases, tar oil, benzene, toluene, and naphthalene.
