Question

Bihar produces % of pyrite of whole India?

1. A. 75
2. B. 85
3. C. 95 (Correct answer)
4. D. 100

Correct Answer

Option C — 95

Detailed Solution & Explanation

The correct answer is 95.

Key Points

• Bihar accounts for about 95% of India's pyrite production, making it overwhelmingly the country's leading producer of this mineral. The deposits are concentrated at Amjhore in the Rohtas district, in the Kaimur region of southern Bihar.
• Pyrite (FeS2), commonly called "fool's gold" because of its metallic lustre and pale brass-yellow colour, is chiefly used in the manufacture of sulphuric acid and sulphur, and hence in the fertiliser industry.
• Bihar's mineral base changed drastically after the bifurcation of the state in 2000, when the mineral-rich Chhotanagpur plateau went to the newly created Jharkhand, taking with it most of the coal, iron ore, copper, bauxite and mica.
• The minerals remaining significant in Bihar today include pyrite, limestone, quartzite, bauxite, mica and small gold reserves.

Exam Tip

• always frame Bihar's mineral questions around the pre- and post-2000 bifurcation position, since that is the usual basis of the trap.
