What happens to iron ore in a blast furnace ...

What happens to iron ore in a blast furnace? The blast furnace Iron ores such as haematite contain iron (III) oxide, Fe 2O 3. The oxygen must be removed from the iron (III) oxide in order to leave the iron behind. In this reaction, the iron (III) oxide is reduced to iron, and the carbon is oxidised to carbon dioxide.
