RAS question
Khetri in Jhunjhunu district is famous for which mineral?
Correct answer: (D) Copper.
Khetri in Jhunjhunu district is famous for copper mining.
Explanation
Khetri is associated with copper, not with gold, zinc or iron. The Khetri Copper Complex is located at Khetrinagar, Rajasthan, under Hindustan Copper Limited, and the Aravalli foothill belt around Khetri is a copper-mineralised zone popularly known as the Khetri Copper Belt. Khetri and Kolihan are mechanised underground mines, with process plants for refined copper. In Rajasthan geography, Khetri is a major copper-mining area, and the Khetri Copper Complex under Hindustan Copper Limited is counted among India's larger copper-producing centres.
Why the other options are wrong
- (A) Gold is not the mineral associated with Khetri; Hindustan Copper Limited connects the area with copper mineralisation and the Khetri Copper Complex.
- (B) Zinc is associated with areas such as Zawar or Agucha, whereas Khetri is a copper-mining centre.
- (C) Iron is linked with other mineral belts, while Khetri is known for its copper belt, copper mines and copper-processing infrastructure.
Concept
Rajasthan's mineral geography links important mining centres with their characteristic minerals. Such location-mineral pairs recur in RAS because they connect physical geography with the state's resource economy.
