When the ore haematite is burnt in air with coke around 2000 o C along with lime, the process not only produces steel but also produces a silicate slag that is useful in making building materials such as cement. Discuss the same and show through balanced chemical equations.

Question

Aditi Chauhan · Answer

Haematite (Fe 2 &shy;O 3 ) on burning with coke and lime at 2000 o C result in the following reactions. C + O 2 &rarr; CO 2 CO 2 + O &rarr; 2CO 3CO + Fe 2 O 3 &rarr; 2Fe + 3CO 2 (Reduction of Fe 2 O 3 to form steel) (steel) SiO 2 + CaO &rarr; CaSiO 3 (Slag, CaSiO 3 is used as building material) (Lime) (Slag)
