Titanium-rich mineral found in India is

Correct option is D

The correct answer is (d) ilmenite

Explanation:
• Ilmenite (iron titanium oxide, FeTiO3) is the primary and most significant ore of Titanium.
• In India, vast reserves of ilmenite are found heavily concentrated in the coastal beach placer sands of Kerala, Tamil Nadu, and Odisha.

Information Booster:
• Titanium derived from ilmenite is extensively used to manufacture titanium dioxide (TiO2), an incredibly bright white pigment used universally in paints, paper, and plastics.
• Rutile (TiO2) is another titanium-rich mineral found alongside ilmenite in Indian beach sands.

Additional Knowledge:
bauxite (Option a)
• Bauxite is the world's primary commercial ore strictly for extracting Aluminum.
dolomite (Option b)
• Dolomite is an anhydrous carbonate mineral composed strictly of calcium magnesium carbonate, used in the steel industry.
chalcopyrite (Option c)
• Chalcopyrite is heavily mined as the most abundant commercial ore for extracting Copper.
None of the above/More than one of the above (Option e)
• Incorrect, as ilmenite accurately fits the metallic criteria.

So the correct answer is (d)
