Limestone is used as a flux in the extraction of
- A Iron
- B Aluminium
- C Zinc
- D Copper
Answer & Solution
Correct Answer
(A) Iron
Step-by-step Solution
Detailed explanation
Limestone is used as a flux in the extraction of iron because it decomposes in hot furnace to form calcium oxide and carbon dioxide. The formed calcium oxide actually acts as flux and combined with silica to form fusible calcium silicate slag.
