The reaction that does not take place in a blast furnace between to temperature range during extraction of iron is:
- A
- B
- C
- D
Solution & Step-by-step Explanation
Reduction of iron oxides occurs in stages. At the lower temperature range (), is reduced to and then to .In the higher temperature range (), is reduced by to (Option B), and coke reacts with to form (Option C). Slag formation (Option D) also occurs here.Option A is the reduction of to , which typically occurs in the cooler, upper part of the furnace.
