2. Chromite
3. Kyanite
4. Sillimanite
In India, which of the above is/are officially designated as major minerals?
(a) 1 and 2 only · (b) 4 only · (c) 1 and 3 only · (d) 2, 3 and 4 only
उत्तर और व्याख्या · explanation in English
Answer: (d) केवल 2, 3 और 4
Chromite, kyanite and sillimanite are major minerals, which the Central Government regulates and the Indian Bureau of Mines tracks in its national mineral inventory. Bentonite is not a major mineral; it is treated as a minor mineral, which States regulate.
- ✗ 1. The Indian Bureau of Mines states that bentonite has been declared a minor mineral under Section 3(e) of the MMDR Act, 1957, so its production is reported to the States, not to IBM, and it is not counted as a major mineral.
- ✓ 2. Chromite, the ore of chromium, is a major (metallic) mineral and is listed in the national mineral inventory.
- ✓ 3. Kyanite is a major mineral and is listed in the national mineral inventory.
- ✓ 4. Sillimanite is a major mineral and is listed in the national mineral inventory.
Remember · Chromite, kyanite and sillimanite are major minerals tracked in the national mineral inventory; bentonite, a clay, is not a major mineral.
