About Lithium
- Lithium, often referred to as “White Gold,” is a soft, silvery-white alkali metal that plays an indispensable role in energy storage, electric mobility, and advanced technologies due to its high energy density and superior electrochemical potential.
Key Properties
- Density: Lightest solid element and least-dense metal.
- Reactivity: Highly reactive and flammable; does not occur freely in nature and is stored under mineral oil or inert conditions.
- Electrochemical Potential: Highest among metals, making lithium highly suitable for rechargeable batteries.
- Geological Occurrence:
Found primarily in two distinct geological formations:
- Pegmatitic Minerals: Hard-rock deposits (e.g., spodumene).
- Brines: Saline groundwater beneath high-altitude salt flats (salars) and geothermal waters.
Global Landscape: Reserves vs. Production
- The Lithium Triangle: A region in South America covering Argentina, Bolivia, and Chile that holds approximately 54% of global lithium reserves beneath its arid salt flats.
| Domain | Key Countries (Rank-Wise) |
| Top Reserves (Resource Base) | Bolivia > Argentina > Chile |
| Top Producers (Extraction) | Australia (Hard-rock mining) > Chile (Brine extraction) > China |
Lithium in India
- Regulatory Classification: Classified as a “Critical and Strategic Mineral” under the MMDR (Mines and Minerals Development and Regulation) Amendment Act, 2023, enabling the Central Government to auction mineral blocks to private players.
- Identified Reserves:
- Reasi District (Jammu & Kashmir): Inferred resources (G3 category) of 5.9 million tonnes discovered in the Salal-Haimna region.
- Mandya (Karnataka): Smaller pegmatite-hosted lithium deposits.
- Potential Belts for Exploration:
- Mica Belts: Rajasthan, Bihar, and Andhra Pradesh.
- Pegmatite Belts: Odisha and Chhattisgarh.
- Brine Sources: Rann of Kutch (Gujarat).
Government Initiatives for Supply Chain Security
- KABIL (Khanij Bidesh India Ltd): A Joint Venture of three Central Public Sector Enterprises—NALCO, HCL, and MECL—mandated to identify, explore, and acquire strategic overseas mineral assets (e.g., acquiring 5 lithium brine blocks in Catamarca, Argentina).
- Mineral Security Partnership (MSP): India joined this US-led international coalition to secure resilient, sustainable, and diversified critical mineral supply chains globally.
- Private Sector Auctioning: Strategic mineral blocks are being competitively auctioned to private entities under the 2023 MMDR framework to boost domestic exploration and mining.
Applications of Lithium
- Lithium-ion batteries: EVs, mobiles, laptops and energy-storage systems.
- Aerospace: Lightweight Al-Li and Mg-Li alloys.
- Nuclear technology: Fusion research and tritium production.
- CO₂ absorption: Lithium hydroxide used in spacecraft and submarines.
Environmental Concerns
- High water consumption: Especially in brine extraction.
- Chemical pollution: Waste, contaminated water and soil degradation.
- Energy-intensive: Mining, processing and refining require significant energy.
- Ecological stress: Can affect groundwater, biodiversity, vegetation and local livelihoods.
