Finegrained iron ore is processed into coarsegrained clumps for use in the blast furnace. Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon. A mixture of iron ore and coal is then heated in a blast furnace to produce molten iron, or pig iron, from which steel is made.
