Metallurgical coal - Wikipedia

Metallurgical coal or coking coal is a grade of coal that can be used to produce good-quality coke.Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that produces coal for coking, to ensure a stable and low-cost supply ...

Steelmaking Coal - Tent Mountain Mine Re-start Project

Steelmaking coal is heated to approximately 1,100º C in oxygen-free coke ovens to prevent combustion and to remove impurities. At this point the coal has become metallurgical coke - a very durable, almost pure form of carbon. Coke is then mixed with iron ore and limestone in a blast furnace to convert the iron ore into pig iron.

How steelmaking may go carbon-free—by dropping its addiction to coal

Purified coal, or "coke," is heated and melted with iron oxide and limestone, then injected with oxygen to reduce the carbon content of the mixture and to remove impurities. Almost all other steel is made from scrap metal that's melted down in an electric arc furnace. This approach doesn't use coke as a raw material.
