In the blast furnace during extraction of iron, the following are main reactions :
(i) Reduction of

F e_{2} O_{3}

F e_{2} O_{3} + CO \to 2 F e O + C O_{2}

2 F e O + 2 CO \to 2 F e + 2 C O_{2}

_________________________

F e_{2} O_{3} + 3 CO \to 2 F e + 3 C O_{2}

(ii) Slag formation

C a O + S i O_{2} \to Fusible slag C a S i O_{3}
