  • Metallurgical CoalIspatGuru

    Sep 25 2018 · Metallurgical coal is also called met coal or coking coal. It is a bituminous coal which allows the production of a coke suitable to support a blast furnace (BF) charge. It is distinguished by the strong low-density coke produced when the coal is heated in a low oxygen (O2) environment or in absence of air to reduce mineral impurities
