metallurgical coal

Metallurgical coal, also known as coking coal, is a type of coal specifically used to produce steel. Unlike thermal coal, which is used primarily for electricity generation, metallurgical coal undergoes a process called coking, where it is heated in the absence of air to create coke. Coke is a porous substance that burns hotter and cleaner, making it essential in the steel-making process. The quality of metallurgical coal is crucial, as impurities can affect steel quality. Its demand is closely linked to the health of the steel industry, impacting economic activity worldwide.
