Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide having a stronger affinity for the oxygen in iron ore than iron does reduces the iron to its elemental form Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace flue gas is in direct contact with the ore and iron allowing carbon monoxide to diffuse into the ore and
