In the blast furnace, what is the primary reducing agent that reduces iron ore to iron?
Correct answer: B. Carbon monoxide (CO)
- A. Carbon (coke)
- B. Carbon monoxide (CO)
- C. Limestone
- D. Oxygen
Explanation
While coke (carbon) is added to the furnace, it primarily burns to produce carbon monoxide (CO). This carbon monoxide gas then acts as the main chemical reducing agent, removing oxygen from the iron oxides to produce molten iron.
