Question

Choose the appropriate option to fill in the blank:
Minerals are classified as:

• A. Energy Minerals
• B. Non-Metallic Minerals
• C. Non-Ferrous Minerals
• D. Precious Minerals

Hint:

Remember:

• Ferrous minerals $\rightarrow$ contain iron.

• Non-ferrous minerals $\rightarrow$ do not contain iron.

• Bauxite $\rightarrow$ Aluminium ore $\rightarrow$ Non-ferrous mineral.

• Gold $\rightarrow$ Precious mineral.

Answer 1

The Correct Option is C

Step 1: Recall what bauxite is.
Bauxite is the main ore used to extract aluminium.
Step 2: Check whether aluminium contains iron.
Aluminium has no iron content at all, and minerals without iron are grouped as non ferrous minerals, alongside copper, lead, zinc and tin.
Step 3: Rule out the other categories.
Bauxite is not used for energy like coal or petroleum, it is not a non metallic mineral like mica or gypsum, and it is not a precious mineral like gold or diamond.
So bauxite belongs under non ferrous minerals, which is option (C).
