Coal mining - Coal preparation Britannica

In the early days of coal preparation, the objective was to provide a product of uniform size and to reduce the content of inert rock materials in ROM coal. Reduction of impurities increased the heating value of the cleaned product, reduced deposits left on the furnace, reduced the load on the particle-removal system, and increased the overall operating performance of the furnace.

Coke (fuel) - Wikipedia

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
