PARLIAMENT QUESTION: MINERALS IN COASTAL BEACHES

In this note

1. At a Glance

Beach Sand Minerals (BSM) are heavy-mineral placer deposits (ilmenite, rutile, leucoxene, zircon, monazite, garnet, sillimanite) concentrated in coastal/teri sands of peninsular India. [1][3]
Classified as "Atomic Minerals" under Part-B of the First Schedule of the MMDR Act, 1957 — strategic for India's three-stage nuclear programme (monazite → thorium). [2][3]
Relevant for UPSC across GS-III (energy security, critical minerals, mining policy) and GS-II (parliamentary oversight via Q&A). [1]

Lok Sabha Parliament Question answered on 11 March 2026 by Department of Atomic Energy disclosed updated state-wise BSM resource inventory (as on December 2025). [1]
Estimated Total Heavy Mineral (THM) resources at 1,309.42 million tonnes including beach sand and inland placers across 8 states. [1]

Atomic Minerals Directorate for Exploration and Research (AMD) — constituent unit of DAE, founded 1949 (as Rare Minerals Survey Unit); mandated to explore U, Th, Nb, Ta, Be, Li, Zr, Ti, REE-bearing and BSM resources. [3]
MMDR Act 1957 placed atomic minerals under Union control; Section 5 restricts mining of atomic minerals above threshold to Government Companies/Corporations. [2]
2016 amendment lowered monazite threshold to 0.00% in THM, tightening state control over monazite-bearing BSM. [2]
Mineral Concession Rules 2016 updated licensing framework. [2]

Parent ministry: Department of Atomic Energy (DAE), under PMO. [1]
Implementing body: Atomic Minerals Directorate (AMD), Hyderabad-headquartered. [3]
Enabling law: Mines and Minerals (Development and Regulation) Act, 1957 — Part-B, First Schedule lists atomic minerals; Section 5 (mining restriction); Section 23C (state rules vs illegal mining). [2]
BSM constituents: Ilmenite, Rutile, Leucoxene, Zircon, Monazite, Garnet, Sillimanite. [3]
8 BSM-bearing states: Andhra Pradesh, Odisha, Tamil Nadu, Kerala, Maharashtra, Gujarat, West Bengal, Jharkhand. [1][3]
Total THM resources (Dec 2025): 1,309.42 Mt. [1]
Monazite resources: ~11.93 Mt (earlier estimate) / 13.15 Mt across 136 deposits (as on 28.01.2026). [2][3]
Monazite REO content: 55–60% Total Rare Earth Oxide; also contains ~9–10% ThO₂. [2]
State leaders (THM, Mt): Andhra Pradesh 359.79, Odisha 351.36, Tamil Nadu (≥191 ilmenite alone). [1]

Economic

BSM yields titanium feedstock (ilmenite/rutile), zirconium, garnet (abrasives), sillimanite (refractories) — import-substitution & export potential. [3]
Monazite is the feedstock for thorium powering Stage-III of India's nuclear programme. [2]

Scientific / Technological

Monazite hosts light Rare Earth Elements (Ce, La, Nd, Pr) critical for magnets, EVs, defence electronics. [2]
AMD uses airborne geophysical surveys, geochemical sampling for resource augmentation. [3]

Legal / Constitutional

Entry 54, Union List — regulation of mines declared by Parliament; atomic minerals fully under Union. [2]
Section 5 MMDR: only PSUs (IREL India Ltd) can mine monazite-bearing sands above threshold. [2]
Section 23C: states make rules against illegal beach sand mining. [2]

Environmental

Coastal mining vs Coastal Regulation Zone (CRZ) Notification 2019 of MoEFCC; ecosystem impact on dunes, turtle nesting. [3]
Radioactive (Th, U) trace risks in monazite tailings — requires AERB-approved handling. [2]

Administrative

11 Mar 2026: Parliament Q&A reveals 1,309 Mt THM inventory across 8 states. [1]
28 Jan 2026: AMD's rare-earth resource update — 136 BSM deposits, 13.15 Mt monazite. [3]
2025: Government policy push on Critical Minerals Mission complementing BSM/REE exploration. [3]
Continued ban on private export of monazite; mining restricted to IREL (India) Ltd. [2]

BSM are listed under Part-B of First Schedule, MMDR Act 1957 (atomic minerals). [2]
AMD is under Department of Atomic Energy, NOT Ministry of Mines. [3]
Monazite contains 55–60% REO and ~9% thorium oxide. [2]
Section 5 MMDR: atomic mineral mining restricted to Government Company/Corporation. [2]
Monazite threshold for atomic-mineral classification = 0.00% in THM (effectively any monazite). [2]
Total THM resources India (Dec 2025): 1,309.42 Mt. [1]
Andhra Pradesh leads in THM (359.79 Mt), followed by Odisha (351.36 Mt). [1]
BSM occur in 8 states — incl. Jharkhand (inland placer) — not just coastal. [1]
Seven BSM minerals: Ilmenite, Rutile, Leucoxene, Zircon, Monazite, Garnet, Sillimanite. [3]
IREL (India) Ltd under DAE is the sole monazite miner. [2]
Section 23C MMDR empowers states against illegal mining. [2]
Teri (red) sands are inland placers in Tamil Nadu/Andhra Pradesh. [3]

GS-III: Energy security; Mineral policy; Critical minerals; Science & Technology (nuclear).
GS-II: Centre-State relations in mining; statutory bodies.
Plausible stems: 1. "Beach sand minerals are central to India's Stage-III nuclear ambition yet remain underexploited. Examine." 2. "Discuss the legal architecture governing atomic minerals in India and the role of AMD and IREL." 3. "Reconciling coastal ecology with critical-mineral extraction is the new frontier of India's resource policy. Critically examine."

IREL (India) Ltd — sole monazite/REE processor under DAE.
Critical & Strategic Minerals list (2023) — 30 minerals notified by Ministry of Mines.
Three-Stage Nuclear Programme — thorium relevance.
MMDR Amendment Act 2023 — auction of critical minerals.
Coastal Regulation Zone Notification 2019 — environmental overlay.
Geological Survey of India (GSI) vs AMD — mandate distinction.
Rare Earth Elements global supply chain — China dependence.
National Mineral Policy 2019.

BSM are atomic minerals (Part-B), not "major minerals" generically — common confusion.
Regulator is AMD/DAE, NOT Ministry of Mines/GSI for atomic minerals.
Monazite mining is not open to private sector (only Government Cos), unlike ilmenite which can be mined privately if monazite < threshold.
Teri sands are inland red sands (TN), not coastal — though grouped with BSM.
AP, not Odisha or Tamil Nadu, currently leads THM resource (Dec 2025 data).
