The overall reaction for the production of iron in a blast furnace is as follows: (23.3.1) F e 2 O 3 ( s) + 3 C ( s) → Δ 2 F e ( l) + 3 C O ( g) The actual reductant is CO, which reduces Fe 2 O 3 to give Fe (l) and CO 2 (g) (Equation 23.3.1 ); the CO 2 is then reduced back to CO by reaction with excess carbon.

Rock that is rich in a valuable mineral is referred to as ore. Most iron ore contains some form of iron oxide (e.g. Fe 2 O 3, Fe 3 O 4). 3 In order to extract iron from iron ore, one must first remove the unwanted minerals, then remove the oxygen from the iron. The latter step can only be achieved with a chemical reaction.
