Amjhor in Bihar is famous for the deposit of which mineral?
- A.Mica
- B.Bauxite
- C.Pyrite
- D.Copper
Correct answer
Explanation
The correct answer is C, pyrite. Amjhor lies in Rohtas district in the Kaimur hills and holds the best known pyrite deposit of India. Pyrite is an iron sulphide, called fool's gold for its colour, and is used to make sulphuric acid, which in turn goes into fertiliser, so the deposit was developed with a fertiliser plan in mind.
Option A, mica, is found in the Gaya, Nawada, Jamui and Munger belt, the thin tail of the Koderma field that stayed with Bihar. Option B, bauxite, occurs in small pockets in Munger, Jamui and Rohtas but in no quantity worth a question. Option D, copper, belonged to the Singhbhum belt and went to Jharkhand in 2000, so Bihar has none, which is exactly the kind of trap this question sets.
