Passage / Comprehension
The common ores of iron are both iron oxides, which can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is inexpensive and provides both the reducing agent for the reaction and the heat source. The most commonly used iron ores are hematite, Fe₂O₃, and magnetite, Fe₃O₄.
The reaction(s) which is/are NOT primarily occur in the reduction zone in the extraction of iron from haematite ore :-
Options:(select one or more)
Answer:
C, D
Solution:
- In the blast furnace, iron oxides are reduced by CO and coke.
- The correct stepwise reduction includes:
- Fe₂O₃ → Fe₃O₄ → FeO → Fe
- CO acts as the main reducing agent, converting FeO to Fe.
- The given reaction Fe₂O₃ + CO → 2FeO + CO₂ is not a correct balanced or standard step in the extraction sequence.
