India’s growing dependence on critical minerals presents challenges to its clean energy transition, industrial competitiveness and strategic autonomy.” Discuss the significance of critical minerals and examine the measures required to secure their supply chains. (10 Marks) (GS 3: Indian Economy — Infrastructure)

Introduction

Critical minerals are minerals essential for economic development, national security and emerging technologies, but whose supply chains face high risks of disruption. Lithium, cobalt, nickel, graphite and rare earth elements are particularly important for India’s energy transition and advanced manufacturing. Securing their supply is therefore central to India’s technological sovereignty and strategic autonomy.

Significance of critical minerals

1. Clean energy transition: Lithium, cobalt, nickel and graphite are essential inputs for batteries used in electric vehicles and grid-scale energy storage.
   Example: Lithium-ion batteries support India’s electric mobility ambitions.
2. Renewable energy generation: Rare earth elements such as neodymium and dysprosium are used in high-performance permanent magnets for wind turbines.
   Example: Direct-drive wind turbines use rare-earth permanent magnets.
3. Electronics and semiconductor industry: Critical minerals are required for semiconductor fabrication, electronic components and advanced communication technologies.
   Example: Gallium and germanium are used in specialised semiconductor and optoelectronic applications.
4. Defence and national security: Advanced weapons systems, radar, aerospace equipment and precision-guided technologies depend on specialised minerals.
   Example: Rare earth-based materials are used in defence electronics and high-performance magnets.
5. Industrial competitiveness: Reliable access to critical minerals supports domestic manufacturing, reduces production uncertainty and strengthens India’s participation in global value chains.
   Example: Battery manufacturing and electric vehicle industries require stable supplies of lithium, nickel and graphite.
6. Strategic autonomy: Concentrated global production and processing create vulnerabilities to geopolitical restrictions and export controls.
   Example: China’s dominance in several rare-earth processing stages highlights India’s exposure to external supply disruptions.

Measures required to secure critical mineral supply chains

1. Domestic exploration and mining: Accelerate geological surveys, exploration and transparent auctioning of mineral blocks to reduce import dependence.
   Legislative measure: The Mines and Minerals (Development and Regulation) Amendment Act, 2023, facilitated private-sector participation in the exploration and mining of critical minerals.
2. Overseas mineral acquisition: Secure mineral assets through international partnerships, investments and long-term supply agreements.
   Institution: Khanij Bidesh India Limited (KABIL) is mandated to identify and acquire strategic mineral assets abroad. Its lithium exploration agreement in Argentina is an important step.
3. Develop domestic processing capabilities: Establish refining, separation and mineral-processing facilities rather than depending on imports of processed minerals.
   Example: Developing domestic rare-earth separation and lithium refining capabilities can strengthen India’s position in the battery and electronics value chains.
4. Promote recycling and urban mining: Recover valuable minerals from discarded batteries, electronic waste and industrial residues.
   Policy: Battery Waste Management Rules, 2022, provide an Extended Producer Responsibility framework for battery collection and recycling.
5. Strengthen international cooperation: Diversify supply sources through partnerships with mineral-rich countries and participation in multilateral initiatives.
   Initiative: India’s participation in the Minerals Security Partnership facilitates cooperation on resilient and diversified critical mineral supply chains.
6. Invest in research and technological innovation: Develop alternative materials, efficient extraction technologies and mineral-efficient manufacturing processes.
   Example: Research into sodium-ion batteries can reduce dependence on lithium for certain energy-storage applications.
7. Establish an integrated institutional framework: Coordinate exploration, mining, processing, recycling and overseas acquisition through a national strategy.
   Initiative: The National Critical Mineral Mission, approved in 2025 with a proposed public expenditure of ₹16,300 crore, aims to strengthen domestic and overseas critical mineral supply chains.

Conclusion

Critical minerals are no longer merely industrial commodities; they are strategic assets underpinning India’s energy transition, technological development and national security. India must adopt a whole-of-supply-chain approach, combining domestic exploration, overseas partnerships, processing capacity, recycling and technological innovation to achieve long-term mineral security.
