Metallurgical coal is converted to coke by driving off impurities to leave almost pure carbon. The physical properties of coking coal cause the coal to soften, liquefy and then resolidify into hard but porous lumps when heated in the absence of air. It is important for metallurgical coal to have low sulphur and phosphorous contents.
Coal, Kentucky Geological Survey, University of Kentucky
Metallurgical coal (also called "met" coal) is an important raw material used in the steel-making process, although very small amounts of coal (relative to the amount used for electricity) are needed. The coal used to make steel is heated without air in an oven at temperatures of as much as 2,060°F (1,125°F), until most of its volatile matter is released.
