The chemical process in the production of steel from haematite ore involves:
Correct answer: D. Oxidation followed by reduction
- A. Reduction
- B. Oxidation
- C. Reduction followed by oxidation
- D. Oxidation followed by reduction
Explanation
The correct answer is Option D: Oxidation followed by reduction. In the production of steel from haematite, the process begins with oxidizing iron ore to form iron oxide by heating it in the presence of oxygen. The iron oxide is then reduced to iron using carbon monoxide as the reducing agent. Option A overlooks the initial oxidation step, Option B ignores the subsequent reduction, and Option C reverses the correct sequence of the process.
