Question

The most important ore of aluminium is:

• A. Bauxite
• B. Magnetite
• C. Haematite
• D. Monazite

Hint:

Match each mineral in the options to the metal it is mined for.

Answer 1

The Correct Option is A

Match each mineral in the list to the metal it is actually mined for. Magnetite and haematite are both iron oxide minerals, they belong squarely to iron metallurgy, so they can be ruled out for this question about aluminium. Monazite is used industrially to obtain thorium and rare earth elements, again not aluminium. Bauxite, however, is almost entirely composed of hydrated aluminium oxide, and nearly all of the aluminium metal produced in the world today starts its journey as bauxite ore mined from open pits. Since the question specifically asks for the ore of aluminium, the only mineral on the list that fits this description is bauxite, option A.
