    Coking Coal For Steel Production And Alternatives Front

    By Noah Beecher Kelk Metallurgical coal also called metcoal or coking coal is a type of coal that is used in the production of steel. It is of a higher purity than thermal coal which is used in energy generation. To make steel metcoal is heated at around 1100 degrees C to remove water and other chemicals. This is done without the presence of oxygen. The result is a lump of near-pure carbon .
