It is an important coking coal for India's steel industry. The sample studied is a middlings fraction produced by jigwashing the runofmine coal. The middlings (~60% of the raw coal) is used by the powergenerating industry to produce electricity, while the clean fraction (~40% of the raw coal) is used for cokemaking3.

Metallurgical coke with high strength and low reactivity is used in the ironmaking blast furnace. Replacement of some coking coal with biocoal was shown to result in lower strength and higher reactivity of produced coke due to introduction of reactive biocoal carbon and ash components catalyzing the Boudouard reaction, but also due to lowering of the coking coal blend fluidity, which ...

Coking coal, or metallurgical coal, has been produced in the United States for nearly 200 years. Coking coal is primarily used in the production of coke for use in the steel industry, and for other uses (for example, foundries, blacksmithing, heating buildings, and brewing). Currently, coking coal is produced in Alabama, Arkansas, Pennsylvania, Virginia, and West Virginia.
