Coking coal and thermal coal are two types of coal that are used for different purposes. Coking coal, also known as metallurgical coal, is primarily used in the production of steel. It has high carbon content and low impurities, making it ideal for the manufacturing of coke, which is a key component in the steelmaking process.

Coking coal must also have low sulphur and phosphorous contents. Almost all metallurgical coal is used in coke ovens. The coking process consists of heating coking coal to around 1000-1100ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in a hard porous material - coke.
