Q. Consider the following minerals: - Bauxite
- Cryolite
- Corundum
- Cassiterite
How many of the above are classified as aluminium ores?
Answer:
Only two
Notes: Bauxite and cryolite are aluminium ores. Corundum, although aluminium oxide, is not considered an aluminium ore due to its industrial use and rarity. Cassiterite is the principal ore of tin, not aluminium. Hence, only bauxite and cryolite among the given options are aluminium ores.
