Q21. Read the given statements and select the correct answer from the options provided: Statement I: The Khetri Copper Complex was established by Hindustan Copper Limited (HCL), a public sector enterprise. Statement II: The complex relies solely on imported copper concentrates and does not process ore from the local Singhana mines.
Explanation
The Khetri Copper Complex was established by the public sector undertaking Hindustan Copper Limited to process local copper ore. While it may occasionally use imported concentrates to supplement production, it was fundamentally designed to process ore from the nearby Khetri and Singhana mines. The assertion that it does not process any local ore is incorrect and factually baseless.

Q22. Identify the correctly matched pair regarding the specific color of Marble and its famous source district in Rajasthan:
Explanation
Bhainslana in Jaipur district is the most famous source for high-quality black marble in Rajasthan. Pink marble is primarily associated with regions like Jalore and Banswara, while Makrana is world-renowned for white marble. Green marble is famously found in Rikhabdev in the Udaipur district. These distinct colors are the result of specific mineral impurities present during the rock’s formation.

Q23. In the context of Rajasthan’s mineral wealth, why is the state often categorized as having a monopolistic advantage in certain sectors?
Explanation
Rajasthan is described as having a monopolistic advantage because it is the sole or dominant producer of certain minerals in India. It accounts for almost 100% of the national production of lead, zinc, and wollastonite. This unique geological endowment makes the state a critical supplier for these minerals, which are essential for various industrial applications ranging from metallurgy to ceramics.

Q24. The rock phosphate deposits in the Jaisalmer district are geographically heavily concentrated in which of the following prominent areas?
Explanation
In Jaisalmer district, rock phosphate deposits are found in the Birmania and Fatehgarh areas. These are typically sedimentary deposits. While Jhamarkotra and Maton are the most famous rock phosphate sites in the state, they are located in the Udaipur district. Zawar is associated with lead and zinc, and Morija-Banol is known for iron ore, distinguishing these geographical regions clearly.

Q25. Which of the following statements regarding Granite in Rajasthan is incorrect?
Explanation
Granite is an intrusive igneous rock, not a sedimentary one. It forms from the slow cooling of magma beneath the earth’s surface and is found across several districts in the Aravalli range and surrounding regions. While it is processed in arid districts like Jalore, its geological origin is igneous. The other statements about its strength, processing industries, and colors are accurate.

Q26. Match the items in List I with those in List II and select the correct answer using the options provided:
Iron Ore Mining Area
District
A. Morija-Banol
i. Udaipur
B. Nathra-Ki-Pal
ii. Dausa
C. Neemla-Raisela
iii. Jaipur
D. Chomu-Samod
iv. Jaipur (Rural/Region)
Explanation
Morija-Banol is the most significant iron ore deposit in the Jaipur district. Nathra-Ki-Pal is a well-known iron ore site located in Udaipur. Neemla-Raisela is a prominent mining area in the Dausa district. Chomu-Samod is another region near Jaipur where iron ore deposits are found. These sites together contribute to the state’s total production of hematite-grade iron ore deposits.

Q27. The distinct properties of Dholpur and Bharatpur sandstone that make them highly desirable for monumental architecture include all EXCEPT:
Explanation
Dholpur and Bharatpur sandstones are valued for their durability, beautiful colors, and the ease with which they can be carved into intricate designs. However, as a sedimentary rock composed of sand-sized mineral particles, sandstone is opaque and does not possess transparency like glass. Its structural and aesthetic qualities make it a preferred choice for monumental construction rather than any optical purpose.

Q28. Consider the following statements about silver production in Rajasthan: I. Silver is primarily recovered during the smelting of zinc and lead concentrates. II. Hindustan Zinc Limited is the principal entity responsible for silver recovery in the state. III. Rajasthan produces only a negligible fraction (less than 1%) of India’s total silver. Which of the above statement(s) is/are correct?
Explanation
Silver in Rajasthan is primarily recovered by Hindustan Zinc Limited during the smelting of lead and zinc concentrates. The state is actually the leading producer of silver in India, contributing nearly the entire national output.

Q30. Consider the following statements about the challenges faced by the mining sector in Rajasthan: I. Depletion of high-grade ores forces industries to rely on complex beneficiation of low-grade ores. II. Strict environmental regulations often require mining projects to undergo rigorous clearance processes. III. Unregulated and illegal mining leads to significant losses to the state exchequer. IV. The mining sector faces absolutely no resistance or issues regarding land acquisition from local communities. Which of the above statement(s) is/are incorrect?
Explanation
Depletion of high-grade ores, strict environmental clearances and illegal mining losses are real problems of the mining sector. There is resistance over land acquisition from local communities, so IV is incorrect.
