The symbol equations for the different stages of the extraction of iron from hematite are: Zone 1: The burning of carbon (coke) to provide heat and produce carbon dioxide:; C (s) + O 2 (g) → CO 2 (g). Zone 2: The reduction of carbon dioxide to carbon monoxide:; CO 2 (g) + C (s) → 2CO (g). Zone 3: The reduction of iron(III) oxide by carbon monoxide:
