Ilmenite and rutile, abundantly available in certain coastal tracts of India, are rich sources of which one of the following?

  1. Aluminium
  2. Copper
  3. Iron
  4. Titanium

Answer

Titanium

  • (a) Aluminium: Incorrect. Ilmenite and rutile are not aluminium ores; aluminium is mainly obtained from bauxite.
  • (b) Copper: Incorrect. These minerals are not copper ores; copper is commonly extracted from ores like chalcopyrite.
  • (c) Iron: Incorrect. Ilmenite contains iron, but it is chiefly valued as an ore of titanium, not as a major iron source.
  • (d) Titanium: Correct. Ilmenite (FeTiO3) and rutile (TiO2) are the principal mineral sources of titanium, found in India’s coastal placer deposits.
