The chemical process in the production of steel from haematite ore involve
(a) reduction
(b) oxidation
(c) reduction followed by oxidation
(d) oxidation followed by reduction
The correct option (d) oxidation followed by reduction
Explanation:
Haematite (Fe2O3) containing FeO is first oxidised to convert FeO to Fe2O3 initially and finally reduced by CO, first to Fe3O4, then FeO and finally to Fe.
