RAS question
India ranks first in the world in the production of which mineral?
Correct answer: (D) Mica (sheet).
India has historically been the world's leading producer of sheet mica, especially muscovite mica.
Explanation
The correct answer is sheet mica. India has historically been the world's leading producer of sheet mica, especially muscovite. The Nellore mica belt extends across part of Nellore district in Andhra Pradesh and is identified as the largest mica-producing area. Other major regions include the Koderma-Giridih-Hazaribagh belt in Jharkhand and the Bhilwara-Ajmer region in Rajasthan. Muscovite sheets serve as insulators in electrical and electronic industries, making sheet mica important from an examination perspective.
Why the other options are wrong
- (A) Coal is incorrect because China and the United States, not India, lead in coal production.
- (B) Iron ore is incorrect because Australia and Brazil are ahead of India in iron ore production.
- (C) Bauxite is incorrect because Australia, not India, is the leading producer of bauxite.
Concept
This question tests your understanding of the geography of India's mineral resources, including their leading producers and major producing belts. In RAS, national production rankings are often linked with Rajasthan locations such as the Bhilwara-Ajmer mica region, connecting economic geography with industrial raw materials.
