A major part of gypsum and silver ore in India is extracted in _______.

  1. A.Bihar
  2. B.Rajasthan
  3. C.Jharkhand
  4. D.Odisha

Correct answer

B. Rajasthan

Explanation

The correct answer is B, Rajasthan. Rajasthan supplies most of India's gypsum and almost all of its silver ore.

Gypsum in Rajasthan is mined mainly in Bikaner, Nagaur, Jaisalmer and Barmer, where it occurs in the dry sedimentary beds of the Thar region; it is used to make cement and plaster of Paris and to treat alkaline soil. Silver comes from the Zawar mines in Udaipur district, where it is won along with the lead and zinc ores, since silver in India is mostly a by product of lead and zinc smelting rather than a mineral mined on its own. Rajasthan is also the leading state for lead, zinc, marble and rock phosphate.

Option A is wrong because Bihar is known for mica and limestone. Option C is wrong because Jharkhand leads in coal, iron ore and copper. Option D is wrong because Odisha leads in iron ore, bauxite, manganese and chromite.

Exam tip: Rajasthan for gypsum, silver, lead, zinc and marble; Odisha for iron ore, bauxite and chromite.
