carbon monoxide. Fe2O3 + 3CO → 2Fe + 3CO2
steam (hot air) to produce CO2 which incontact with Coke produce CO that act as the reducing agent to reduce the iron Ore (hematite) Fe2O3 on stages at high temperatures C + O2 --------CO2 CO2+C --------2CO 2Fe2O3 +CO -------(230C)-----2Fe3O4 + CO2 Fe3O4 + CO -------(300)-----3FeO + CO2 FeO + CO --------(800)------ Fe + CO2
