What Happened
- In an unusual parliamentary occurrence, the presiding officer of the Lok Sabha — TDP leader Krishna Prasad Tenneti, who was in the Chair during Question Hour — participated in asking a question about balancing rare earth mineral exploitation with environmental protection.
- The minister's response clarified that beach sand minerals (BSMs) are extracted from coastal deposits and geological rock formations, and acknowledged past illegal monazite extraction through the abuse of graphite exploration licenses (2014-15 onwards).
- The minister noted that India does not rely on China for rare earth minerals and highlighted nuclear sector reforms and the new SHANTI Act (Strategic Harnessing of Advanced Nuclear Technologies for India) as measures to boost domestic rare earth development.
- Budget 2026-27 introduced zero customs duty on monazite imports and announced rare earth corridors in Andhra Pradesh, Odisha, and Kerala.
- The exchange reflects the tension between India's strategic need for rare earths (essential for advanced defence, electronics, and clean energy) and environmental protection of coastal ecosystems.

Beach Sand Minerals and India's Rare Earth Endowment
India's coastal regions — particularly in Kerala, Tamil Nadu, Andhra Pradesh, and Odisha — contain economically significant deposits of "beach sand minerals" (BSMs): garnet, ilmenite, leucoxene, monazite, rutile, sillimanite, and zircon. These heavy minerals concentrate in alluvial coastal sands through natural weathering processes. India holds the world's fifth largest rare earth reserves (approximately 6.9 million tonnes). Crucially, India has approximately 10.70 million tonnes of monazite reserves — containing about 9.63 lakh tonnes of thorium oxide — placing India among the top three global thorium holders.
- India's rare earth reserves: ~6.9 million tonnes (fifth largest globally)
- Monazite reserves: ~10.70 million tonnes (AMD, Department of Atomic Energy estimate)
- Thorium content: ~9.63 lakh tonnes thorium oxide in monazite reserves
- Key rare earth-bearing states: Kerala (largest monazite), Tamil Nadu, Andhra Pradesh, Odisha, Jharkhand
- BSM ore contains: Ilmenite (titanium), rutile (titanium), zircon (zirconium), monazite (rare earths + thorium), garnet, sillimanite
- IREL (India) Ltd: Government of India undertaking; primary BSM mining entity
Connection to this news: The presiding officer's question about balancing exploitation with environment reflects the core dilemma — India's BSM deposits are located in ecologically sensitive coastal zones where mining carries significant risks to beach ecosystems, coastal erosion, and local livelihoods.
Monazite as a Prescribed Substance: Regulatory Regime
Monazite is classified as a "prescribed substance" under the Atomic Energy Act, 1962 (amended 2006) because it contains thorium and uranium — radioactive elements with nuclear applications. This designation places monazite extraction, processing, and trade under strict Department of Atomic Energy (DAE) oversight, limiting private sector participation. Mining rights for prescribed substances vest exclusively with the central government. The Atomic Minerals Directorate for Exploration and Research (AMD), under DAE, is responsible for exploration and inventory of atomic minerals including monazite.
- Atomic Energy Act, 1962: Prescribes substances critical for nuclear programme; mining only by government entities or licensed operators
- Prescribed substances: Uranium, thorium, beryllium, lithium isotopes, and their compounds including monazite
- AMD: Atomic Minerals Directorate for Exploration and Research — government survey and inventory agency under DAE
- IREL (India) Ltd: The primary government entity mining BSMs including monazite
- Past illegality: Graphite mining licenses were misused to extract monazite (smuggling issue) — the minister's reference to 2014-15 graphite-monazite smuggling
- Budget 2026-27: Zero duty on monazite imports (to supplement domestic supply for nuclear fuel cycle)
Connection to this news: The illegal extraction through graphite licenses underscores how the stringent regulatory regime around monazite creates incentives for workarounds — a governance challenge that required both enforcement action and regulatory reform in the nuclear sector.
India's Three-Stage Nuclear Programme and Thorium's Strategic Role
Conceptualised by Dr. Homi J. Bhabha in the 1950s, India's three-stage nuclear power programme is specifically designed around the country's abundant thorium reserves. India has only 1-2% of global uranium reserves but approximately 25% of global thorium — thorium cannot be used directly as nuclear fuel but can be converted into fissile uranium-233 through neutron bombardment. The programme proceeds: Stage 1 (natural uranium heavy water reactors generating plutonium) → Stage 2 (fast breeder reactors using plutonium, breeding uranium-233 from thorium) → Stage 3 (advanced thermal reactors running on uranium-233/thorium cycle).
- Stage 1: Pressurised Heavy Water Reactors (PHWRs) — largely operational (e.g., NPCIL fleet)
- Stage 2: Prototype Fast Breeder Reactor (PFBR), 500 MWe, Kalpakkam — received regulatory approval for core loading in August 2024
- Stage 3: Thorium-fuelled Advanced Heavy Water Reactors — still in development phase
- Estimated energy potential: 500 GWe for at least 4 centuries from India's economically extractable thorium
- India's nuclear power target: 100 GW nuclear capacity by 2047 (Viksit Bharat target)
- SHANTI Act: Strategic framework to accelerate private sector participation in nuclear energy development
Connection to this news: The rare earth corridor announcement and zero-duty on monazite imports reflect recognition that India must optimise extraction of its own BSM deposits to fuel the three-stage nuclear programme — which is itself a core national energy security strategy.
