Metallurgical or coking coal is a primary ingredient in the steel making process. More than twothirds of global steel is produced in basic oxygen blast furnaces. China is the largest consumer of premium coking coal in the world. Coking coal, generally known as metallurgical coal, is a naturally occurring sedimentary rock.
