In blast furnace, the iron oxide is reduced by

Near the top of the blast furnace, iron oxides are reduced to …… by carbon monoxide .

The chief ores of iron are haemalite (Fe_2O_3) , magnetite (Fe_3O_4) , limonite (FeO(OH)) and siderite (FeCO_3) .In the extraction of iron , oxides ores of iron, after concentration through calcination/roasting in reverberatory furnace are mixed with lime stone and coke and fed into a blast furnace. Here, the oxide is reduced to the metal. Reducing species in the extractive metallurgy of iron from haematite ore is :
