🗞️ Why in News Union Budget 2026-27 announced dedicated Rare Earth Corridors in Odisha, Kerala, Andhra Pradesh, and Tamil Nadu to create integrated rare earth mining, processing, and manufacturing ecosystems — directly targeting India’s over-reliance on China’s ~90% dominance in global rare earth processing.
What Are Rare Earth Elements?
Rare Earth Elements (REEs) are a group of 17 metallic elements comprising:
- 15 Lanthanides (Lanthanum to Lutetium on the periodic table)
- Scandium (Sc)
- Yttrium (Y)
Despite the name “rare,” most REEs are relatively abundant in the Earth’s crust — but they rarely occur in economically exploitable concentrations. The real scarcity is in processing capacity.
Why Are REEs Critical?
| Application | REEs Used |
|---|---|
| Electric vehicle motors | Neodymium, Dysprosium (permanent magnets) |
| Wind turbine generators | Neodymium, Praseodymium |
| Defence electronics, guidance systems | Neodymium, Samarium |
| Smartphones, hard drives | Neodymium, Terbium, Dysprosium |
| Catalysts (petroleum refining) | Lanthanum, Cerium |
| Phosphors (LEDs, displays) | Europium, Terbium, Yttrium |
| Medical imaging (MRI) | Gadolinium |
Without REEs, there are no EV motors, no wind turbines, no precision guided missiles — making them a 21st-century strategic resource.
China’s Dominance: The Core Problem
| Metric | China’s Share |
|---|---|
| Global REE mining | ~60–70% |
| Global REE processing | ~90% |
| Global production of REE permanent magnets | ~90% |
| Separation and refining capacity | Near-monopoly |
China’s dominance is not just in mining but critically in separation and processing — the technically complex and environmentally messy part of turning REE ore into usable metals. This creates a structural dependency for every country that wants to build EVs, turbines, or modern defence systems.
China’s REE Export Controls
- 2010: China cut REE export quotas by ~40%, triggering a global supply shock; WTO ruled against China’s restrictions (2014)
- 2023–25: Progressive tightening of export controls on gallium, germanium, graphite, antimony
- 2026: Risk of further restrictions as US-China tech war intensifies
India’s REE Endowment
India is among the world’s leading holders of REE reserves:
| Mineral | Location | Significance |
|---|---|---|
| Monazite (contains Th, La, Ce, Nd) | AP, Tamil Nadu, Kerala, Odisha (beach sands) | 2nd largest thorium reserves globally |
| Ilmenite, Zircon, Rutile | Kerala (Chavara), AP (Srikakulam), Odisha | Beach placer deposits |
| REE in carbonatites | Jharkhand, Andhra Pradesh | Hard rock deposits |
IREL (India Rare Earths Limited) — a PSU under the Department of Atomic Energy — currently operates REE beach sand mining and initial processing.
The Processing Gap
India can mine REE-bearing minerals but lacks commercial-scale separation and refining capacity. Currently, much of India’s monazite concentrate is processed by IREL for thorium (nuclear programme) — the REE byproducts are largely underutilised.
The Rare Earth Corridors Concept
Four States Selected
| State | REE Advantage |
|---|---|
| Odisha | Monazite beach sands; Odisha Mineral Development Corporation active |
| Kerala | Chavara REE deposits; IREL’s oldest processing facility |
| Andhra Pradesh | Beach placer deposits in Srikakulam, Visakhapatnam belt |
| Tamil Nadu | REE deposits in Kanniyakumari, Tirunelveli districts |
What a “Corridor” Means
An integrated corridor would link:
- Mining (extraction of REE-bearing ores)
- Beneficiation (concentration of ore)
- Separation (individual REE elements separated — the currently missing step)
- Alloy/metal production (REE metals and alloys)
- Downstream manufacturing (permanent magnets, phosphors, catalysts)
This vertical integration is exactly what China built over 30 years — and what India needs to replicate.
November 2025 Scheme: Sintered Rare Earth Permanent Magnets
A foundational scheme announced in November 2025 (outlay: Rs 7,280 crore) supports manufacturing of sintered rare earth permanent magnets — the end product needed for EV motors and wind turbines. The Rare Earth Corridors build on this by creating the upstream supply chain.
UPSC Relevance
Prelims: REEs = 17 elements (15 lanthanides + Sc + Y), monazite deposits in India, IREL under DAE, China’s ~90% processing share, four corridor states.
Mains (GS3 — Economy/Science & Technology):
- Critical mineral security as a component of India’s strategic autonomy — parallels with rare earth dependence and China’s export restriction history
- How can India use its REE endowment to become a manufacturing hub for clean energy and defence electronics?
- Role of PSUs vs. private sector in REE processing — IREL vs. private firms
