RAS question
Rampura-Agucha mine in Bhilwara district is one of the world's largest mines for:
Correct answer: (C) Lead-Zinc.
Rampura-Agucha mine in Bhilwara district is one of the world's major lead-zinc mining sites.
Explanation
Rampura-Agucha is associated with lead-zinc, not gold, marble, or copper. It is India's largest and one of the world's big underground lead-zinc mining sites, operated by Hindustan Zinc Limited, with large zinc-lead ore reserves. The Rajasthan Department of Mines and Geology supports the classification by placing Rampura-Agucha in its "Lead, Zinc and Silver" deposits for Bhilwara and listing lead and zinc grades for the site. Lead-Zinc is correct because both the district location and the mineral pairing match the official mineral-deposit listing.
Why the other options are wrong
- (A) Gold is wrong because gold is not a major mineral at Rampura-Agucha, and the official listing places Rampura-Agucha under lead, zinc and silver deposits instead.
- (B) Marble is wrong because Rampura-Agucha is in Bhilwara, while marble is mainly associated with Makrana in Nagaur.
- (D) Copper is wrong because copper mining is centred at Khetri, and the Department of Mines and Geology page lists Rampura-Agucha separately under lead, zinc and silver rather than copper.
Concept
Rajasthan's mineral geography depends on district-wise associations of major mining belts. RAS repeatedly covers mineral location, resource type and regional economy as core static facts in Rajasthan geography.
