Calcination is used in metallurgy for removal of
Calcination is used in metallurgy for removal of
Show Hint
Calcination → removes water and CO$_2$, roasting → removes sulphur.
Updated On: Apr 16, 2026
- water and sulphide
- water and CO$_2$
- CO$_2$ and H$_2$S
- H$_2$O and H$_2$S
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Calcination involves heating ore in absence of air.
Step 1: Effect of calcination.
Removes volatile impurities.
Step 2: Impurities removed.
Moisture (H$_2$O) and CO$_2$ are removed.
Step 3: Conclusion.
