Q1Consider the following statements about the rationalized graphite royalty rates approved on 12 November 2025: 1. Graphite with 80% or more fixed carbon attracts 2% of Average Sale Price on an ad valorem basis. 2. Graphite with less than 80% fixed carbon attracts 4% of Average Sale Price on an ad valorem basis. 3. Graphite continues to be charged only on a fixed rupees-per-tonne basis. Which of the statements given above are correct?
Statements 1 and 2 reproduce the approved grade-wise graphite rates: 2% for graphite with at least 80% fixed carbon and 4% for graphite below that threshold, both on an ad valorem basis. Statement 3 is incorrect because the decision replaced the rupees-per-tonne basis used since September 2014.
Q2Assertion (A): The rationalized graphite royalty was placed on an ad valorem basis. Reason (R): Graphite prices vary across grades, so an ad valorem royalty allows royalty accruals for different grades to reflect price changes proportionately. Select the correct answer:
Both statements are correct, and the Reason explains the Assertion. Graphite had been charged on a rupees-per-tonne basis since 1 September 2014. Because its prices vary across grades, the new ad valorem basis makes royalty accruals for each grade respond proportionately to changes in that grade's price.
Q3On 12 November 2025, the Union Cabinet approved rationalized royalty rates for which group of four critical minerals?
The Cabinet decision dated 12 November 2025 specifically covered graphite, caesium, rubidium and zirconium. Lithium, tungsten, rare earth elements and niobium were mentioned separately as associated critical minerals that may also be unlocked through mining.
Q4Which one of the following correctly states the rationalized royalty rate for zirconium approved on 12 November 2025?
Zirconium carries a royalty of 1% of the Average Sale Price of zirconium metal, chargeable on the zirconium metal contained in the ore produced. The 2% and 4% figures belong to other minerals or graphite grades, so they cannot be substituted here.
Q5Match List I with List II and select the correct answer. List I (Mineral): 1. Graphite; 2. Zirconium; 3. Caesium; 4. Rubidium List II (Use or significance): a. Primary anode material in electric-vehicle batteries; b. Nuclear energy and aerospace; c. Atomic clocks and high-precision instruments; d. Specialty glass for fibre optics and telecommunication systems
Graphite is the primary anode material in electric-vehicle batteries; zirconium is used in nuclear energy and aerospace; caesium is used in atomic clocks and other high-precision instruments; and rubidium is used in specialty glasses for fibre optics and telecommunication systems. Thus, 1-a, 2-b, 3-c and 4-d is the complete match.
