Caking coal, also known as coking coal, is a type of high-quality coal that possesses the unique ability to transform into coke when heated in the absence of air. Coke is a crucial component in the steelmaking process as it provides the required heat and carbon for iron ore reduction. Besides its technical significance, caking coal is also recognized by various synonyms. Some common alternatives for caking coal include metallurgical coal, bituminous coal, carbonaceous coal, or even simply 'coke coal.' These terms are often used interchangeably in industrial and mining sectors, emphasizing the importance and versatility of this vital source of energy and raw material.
