The primary chemical reaction for reducing iron ore to iron is represented by: Fe 2 O 3 + 3CO → 2Fe + 3CO 2. This reaction illustrates how carbon monoxide acts as a reducing agent, converting the iron(III) oxide (rust) to metallic iron, whilst itself turning into carbon dioxide in the process.

The shaft furnace is where iron ore is converted to metallic. Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a ...
