(a) Formation of CO (reducing agent):
$$2C + O_2 \rightarrow 2CO$$
(b) Reduction of haematite:
$$Fe_2O_3 + 3CO \rightarrow 2Fe + 3CO_2$$
(c) Slag formation (flux = limestone → CaO):
$$CaCO_3 \rightarrow CaO + CO_2$$
$$CaO + SiO_2 \rightarrow CaSiO_3 (slag)$$
$$Slag: CaO + SiO_2 \rightarrow CaSiO_3$$

Nicely solved. For the exam, write the final boxed answer clearly to avoid losing marks.
