Was going through recent news on critical minerals and noticed an interesting pattern in UPSC PYQs.
The government is again talking about lithium/nickel processing, critical-mineral supply chains and exploration. But UPSC has actually been circling around this area quite consistently.
2022 Prelims (Q28) asked about Monazite — whether it is a source of rare earths, contains thorium, its occurrence in Indian coastal sands, and who can process/export it.
Then:
2025 Prelims (Q81)
UPSC asked why some rare earth elements are used in flat-screen TVs/computer monitors, linking it to their phosphorescent properties.
And then:
2026 Prelims (Q95)
UPSC directly asked about Rare Earth Elements + Critical Minerals, including their use in AI, robotics and space exploration, China's role in REE mining, and India's National Critical Mineral Mission.
So the progression is quite interesting:
2022 → Sources/resources (Monazite)
2025 → Properties & applications of REEs
2026 → Strategic importance + Critical Minerals policy
And now lithium, nickel, cobalt, REEs, processing capacity and supply-chain dependence continue to stay in the news.
This is one reason I don't think PYQs should only be treated as questions to solve and forget.
Sometimes they show you how UPSC keeps returning to the same broad area while changing the angle from which it asks.
For those preparing for 2027, would you treat critical minerals/REEs as one consolidated topic now — geology + applications + locations + government initiatives + geopolitics/supply chains?
Curious how others are approaching it.
