Question

The chemical process in the production of steel from haematite ore involves

easy

Solution

Correct option is

Oxidation followed by reduction

In haematite, some FeO is also present alongwith Fe₂O₃. Thus, first of all this FeO is oxidised to Fe₂O₃ and after that the Fe₂O₃ gets reduced to Fe₃O₄ and then FeO and finally to Fe. Hence, in this process, first oxidation occurs and after that reduction takes place.
