Extraction of Iron - Online Math Learning

We can extract the iron by reacting the iron oxide with a more reactive element. The more reactive element takes away the oxygen. The raw materials are Haematite (iron ore), Coke (impure C), Limestone (CaCO 3) Make a strong reducing agent. C + O 2 → CO 2. CO 2 + C → 2CO. Reduce the iron 3. Fe 2 O 3 + 3CO → 2Fe + 3CO 2.
