Select the correct statement:
Show Hint
Calcination involves heating an ore in limited oxygen; calcium carbonate decomposes endothermically.
Updated On: Dec 26, 2024
- Roasting involves heating the ore in the absence of air.
- Calcination involves heating the ore above its melting point.
- Smelting involves heating the ore with a suitable reducing agent and flux below its melting point.
- Calcination of calcium carbonate is endothermic.
