What is the role of limestone during the extraction of iron from haematite ore?
- A Leaching agent
- B Oxidising agent
- C Reducing agent
- D Flux
Answer & Solution
Correct Answer
(D) Flux
Step-by-step Solution
Detailed explanation
During extraction of iron from haematite ore, roasted ore, along with coke and limestone is heated in blast furnance. Here coke behaves as reducing agent and limestone is worked as flux. In this process, in reducing zone \(\left(400-900^{\circ} \mathrm{C}\right)\), spongy iron…
