Why are critical minerals essential for the economic development and national security in India ?
Critical minerals are elements and compounds that have diverse, irreplaceable industrial applications but face severe supply chain vulnerabilities due to geographical concentration or sourcing challenges.
The Ministry of Mines has identified 30 critical minerals for the country, with 24 specific strategic minerals (including Lithium, Cobalt, Nickel, Graphite, and Rare Earth Elements) brought under the exclusive auctioning jurisdiction of the Central Government. To secure these, the Union Cabinet approved the National Critical Minerals Mission (NCMM) to aggressively advance domestic exploration, processing, and recycling. http://Geography Optional 2027 pyqs https://www.directionias.com/download-materials/
Geographical Distribution of Critical Minerals in India and Their Geological Origins
The distribution of critical minerals in India is highly correlated with specific geological formations, ranging from ancient cratonic rocks to coastal plains.
Beach Placer Deposits (Coastal Belts)
Ultramafic Complexes and Lateritic Belts
Hard-Rock Inland Alkaline & Carbonatite Complexes
Metamorphic Terrains and Cratonic Margins
Hydrothermal Pegmatites and Bauxite Residuums
Essential for Economic Development
Critical minerals are the bedrock of India’s modern industrial ambitions, fueling sustainable growth across three primary frontiers:
The Clean Energy Transition
India has set ambitious targets of achieving 500 GW of non-fossil fuel capacity by 2030 and reaching Net Zero emissions by 2070.
High-Tech Manufacturing and Electronics
India’s digital transformation depends on advanced electronics, semiconductors, and telecommunications equipment (5G/6G grids).
Agrarian Productivity and Food Security
Essential for National Security
In an increasingly volatile geopolitical landscape, critical minerals are strategic assets directly tied to territorial defense and economic resilience.
Defense Systems and Aerospace
Modern military hardware requires high-strength, lightweight, and heat-resistant materials.
Breaking Geopolitical Strangleholds (Supply Chain Resilience)
The global critical mineral supply chain is highly monopolized. China controls nearly 60% of worldwide extraction and over 85% of rare earth processing and magnet production.
Transitioning Energy Security
As India transitions away from a heavy reliance on imported fossil fuels (crude oil from the Middle East), it must avoid replacing that vulnerability with a dependency on imported green tech minerals. Securing domestic minerals ensures that India’s energy transition is self-sustaining.
Way Forward Recognizing these stakes, India has shifted into high gear with proactive mineral diplomacy and domestic policy overhauls:
Domestic Infrastructure:
The Government announced Dedicated Rare Earth Corridors across Odisha, Kerala, Andhra Pradesh, and Tamil Nadu to seamlessly link mining, refining, and manufacturing ecosystems. These corridors directly complement the existing presence of IREL (India) Limited in Odisha and Kerala.
Long-term significance of rare earth corridors for India
Over the long term, rare earth corridors have the potential to transform India’s position in global supply chains by enabling value addition and technological capability. If implemented effectively, the corridor approach can:
IREL (India) Limited, formerly Indian Rare Earths Limited, has been operating under the Department of Atomic Energy since 1963. With a processing capacity of 10 lakh tonnes per annum, it produces strategic minerals such as ilmenite, rutile, zircon, sillimanite, and garnet.
Importantly, IREL runs a Rare Earth Extraction Plant in Odisha Chhatrapur in the Ganjam district and a Rare Earth Refining Unit at Aluva in Kerala, both of which align with the corridor initiative. By integrating IREL’s established facilities with the new corridors, the government aims to expand domestic rare earth capacity, foster advanced manufacturing, and accelerate India’s transition toward self-reliance and clean energy.
Strategic Importance and Resource Potential of Rare Earth Permanent Magnets in India
Rare Earth Permanent Magnets (REPMs) are among the strongest types of permanent magnets, known for their high magnetic strength and stability. Their compact size and powerful performance make them indispensable for advanced engineering applications such as electric vehicle motors, wind turbine generators, consumer and industrial electronics, aerospace systems, defence equipment, and precision sensors.
As India expands its manufacturing footprint in clean energy, advanced mobility, and strategic sectors, a reliable domestic supply of REPMs is critical. It not only reduces import dependence but also strengthens India’s competitiveness in global value chains for advanced materials.
Global Collaborations:
Through KABIL (Khanij Bidesh India Limited), KABIL is a joint venture of National Aluminium Company Ltd. (NALCO), Hindustan Copper Ltd. (HCL), and Mineral Exploration & Consultancy Ltd. (MECL) under the Ministry of Mines.
India has secured overseas lithium brine assets in Argentina and exploration blocks in Australia. Bilaterally, India signed a critical minerals framework agreement with the US under the Quad Critical Minerals Initiative to coordinate public-private investments and secure a resilient, friendly supply loop outside monopolized markets.
Environmental and strategic concerns of Rare Earth Corridors
While rare earth elements are essential for clean and advanced technologies, their extraction and processing raise significant environmental and strategic concerns. Rare earth mining generates large volumes of waste and often involves radioactive elements such as thorium and uranium, posing risks to ecosystems and human health if not properly managed. The key concerns associated with rare earth elements include:
