Q52. Which of the following options represents the most appropriate long-term solution for tackling the challenges of low-grade mineral ores in Rajasthan?
Explanation
As high-grade mineral reserves are depleted, the long-term sustainability of Rajasthan’s mining sector depends on using low-grade ores. Investing in advanced mineral beneficiation and metallurgical research is the most appropriate solution. This allows for the efficient removal of impurities and the upgrading of ore quality, ensuring that the state’s vast but low-grade resources can be utilized effectively for industry.
Q53. Identify the incorrectly matched pair regarding the specific mineral and the district it is prominently found in:
Explanation
Tungsten is primarily found in the Nagaur (Degana) and Sirohi districts of Rajasthan. Jaisalmer is not associated with tungsten; it is famous for limestone, sandstone, and hydrocarbons. Gypsum is correctly matched with Bikaner, rock phosphate with Udaipur (Jhamarkotra), and limestone with Chittorgarh, which is the hub of the state’s cement industry. Identifying these regional concentrations is key to understanding geology.
Q54. The Kawas and Uttarlai regions in the Barmer district are prominently recognized for extensive deposits of which non-metallic mineral?
Explanation
The Kawas and Uttarlai regions in the Barmer district are well-known for their extensive gypsum deposits. These areas, along with other sites in Bikaner and Nagaur, form the core of Rajasthan’s gypsum-producing landscape. The gypsum found here is utilized in various sectors, ranging from the manufacture of cement and plaster to its vital role in improving the quality of soil.
Q55. The concept of "sustainable mining" as emphasized in Rajasthan’s modern mineral policies fundamentally aims to balance which two major factors?
Explanation
Sustainable mining as promoted in modern policy aims to balance the economic benefits of mineral extraction with the necessity of environmental protection. It involves implementing zero-waste mining techniques, mandatory land reclamation, and minimizing the ecological footprint of mining activities. This approach ensures that mineral resources contribute to current economic growth without compromising the environmental health and resource availability for future generations.
Q56. In the context of Rajasthan’s polymetallic deposits, silver is systematically recovered as an extremely valuable by-product primarily at which major smelting facilities?
Explanation
Silver is systematically recovered as a by-product during the smelting of lead and zinc at the Chanderiya and Debari facilities. These plants, operated by Hindustan Zinc Limited, use advanced metallurgical processes to separate precious metals from base metal concentrates. Because silver is naturally present in the ores from Zawar and Rampura-Agucha, these smelters are the primary sites for national production.Answer key for these questions

Frequently asked questions
How many RAS Prelims practice MCQs are there on Minerals of Rajasthan: Metallic and Non-Metallic?
This page has 56 practice MCQs on Minerals of Rajasthan: Metallic and Non-Metallic (Rajasthan Geography). Each has the correct answer, and most have an explanation.
Where did the Taj Mahal’s marble come from?
From Makrana in the Nagaur district of Rajasthan. Makrana marble is white and fine-grained, and it was also used for the Victoria Memorial in Kolkata, and Makrana is still a major centre of the marble trade.
Where is rock phosphate mined in Rajasthan?
At Jhamarkotra in Udaipur district, the largest deposit in India, and at Birmania and Fatehgarh in Jaisalmer. It is used to make phosphatic fertilisers like SSP and DAP.
What is Jamsar known for?
Jamsar, near Bikaner, is a large gypsum mine. Gypsum is used in cement, plaster and as a soil amendment to reclaim alkaline and saline land, and Rajasthan dominates India’s gypsum production.
