Blast furnace - Wikipedia

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 ...

Production of High-Carbon Ferromanganese in Blast Furnace

Nov 14, 2013  Some deleterious components can be partially removed from the ore prior to melting by dense-medium separation or flotation. Slaging components (dolomite or limestone) can be added to the sintered or pelletized ore, which result in cost savings in the blast furnace. Partial reduction of the higher manganese oxides may also occur during sintering.
