why are iron iii oxide carbon and limestone necessary in a blast furnace

Creating Iron | HowStuffWorks

­The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ­). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

How does the blast furnace work? - …

The hot air blast to the furnace burns the coke and maintains the very high temperatures that are needed to reduce the ore to iron. The reaction between air and the fuel generates carbon monoxide. This gas reduces the iron (III) oxide in the ore to iron.

Iron and Steel corrode quickly. The corrosion of Iron and Steel with water and air is known as rusting. Iron reacts with oxygen in water to form rust, known as hydrated Iron(III) Oxide, Fe₂O₂.2H₂O. Iron + Oxygen + Water → Hydrated Iron(III) Oxide 4Fe + 3O₂ + 4H₂O → Fe₂O₂.2H₂O Water and Oxygen are both required for Iron to rust.
