Which of the following was named as a secondary resource for recovering critical minerals?
- A.Coal fly ash
- B.River sand
- C.Limestone dust
- D.Sea salt
Correct answer
Explanation
The correct answer is coal fly ash. Addressing the symposium on critical minerals and rare earths, the NITI Aayog Member highlighted the scope for recovering critical minerals from secondary resources, naming coal fly ash, red mud, mine tailings and electronic waste. Option B is wrong because river sand was not among the sources named, and sand mining is a separate question of construction material. Option C is wrong because limestone dust did not figure in the list; limestone is a bulk mineral used in cement and steel. Option D is wrong because sea salt was not mentioned, though recovery of minerals from brine is a different line of research. The wider argument was that the sector must move beyond a mine-centric approach and translate laboratory research into commercially viable technology.
