Read this question in English
Ilmenite and rutile, abundantly available in certain coastal tracts of India, are rich sources of which one of the following?
(a) Aluminium · (b) Copper · (c) Iron · (d) Titanium
उत्तर और व्याख्या · explanation in English
Answer: (d) टाइटेनियम
Ilmenite and rutile are the main ores of titanium. They occur in the heavy-mineral beach sands of coasts such as those of Kerala and Tamil Nadu, and titanium dioxide made from them is the white pigment used in paints and toothpaste.
- ✓ (d) Titanium oxide is obtained from the minerals rutile, ilmenite and anatase; ilmenite is found in beach sands along the Kerala and Tamil Nadu coast.
- ✗ (c) Ilmenite does contain iron (it is an iron-titanium oxide), but it is mined for titanium; India's iron comes from haematite and magnetite ores.
- ✗ (a) Aluminium is obtained from bauxite, not from ilmenite or rutile.
Remember · Beach-sand minerals: ilmenite and rutile give titanium; monazite gives thorium. Bauxite gives aluminium; haematite and magnetite give iron.
