India is rapidly advancing in rare earth elements (REE) mining. New discoveries in Rajasthan and Andhra Pradesh show its growing potential. The country aims to become a global hub for strategic minerals essential to modern technology and clean energy. This progress is supported by government initiatives, research institutions, startups, and skill development programmes.
Significance of Rare Earth Elements
Rare earth elements are vital for electronics, defence, aerospace, and green energy. They include 15 lanthanides plus scandium and yttrium. REEs are classified into Light Rare Earth Elements (LREE) and Heavy Rare Earth Elements (HREE). Their unique properties such as thermal stability and luminous intensity make them indispensable in advanced technologies.
India’s Resource Mapping and Discoveries
Scientific bodies like the CSIR-National Geophysical Research Institute have identified LREE deposits in Andhra Pradesh’s Ananthapur district. Rajasthan’s Sirohi and Bhilwara districts are also emerging as key sites for neodymium and other REEs. These resources are crucial for India’s strategic autonomy in technology sectors.
Government Initiatives and Policy Support
The National Mineral Mission promotes innovation, sustainable extraction, and recycling of minerals. Mineral Outreach Forum connects government, industry, and academia to build a Make in Mining India ecosystem. District Mineral Foundations ensure mining benefits local communities and encourage responsible development.
Research Ecosystem and Centres of Excellence
India has established Centres of Excellence at premier institutions such as IIT Bombay, IIT Hyderabad, and CSIR labs. These CoEs follow a Hub & Spoke model encouraging collaboration among government, industry, MSMEs, and investors. They focus on critical mineral research supporting sectors like clean energy, aerospace, and space technologies.
Technological Innovation and Sustainable Practices
Cutting-edge technologies like AI, machine learning, and automation are integrated into mining research and operations. Sustainable methods such as bioleaching and e-waste recycling are promoted to reduce environmental impact. Collaborations have developed applications like rare earth phosphate coatings for biodegradable implants.
Skill Development and Industry 4.0 Integration
Skilling initiatives include apprenticeships at Indian Rare Earth Limited and training through the National Institute of Rock Mechanics. Digital tools like MATLAB and simulation software are taught in universities. Platforms like NPTEL and Atal Tinkering Labs encourage innovation in IoT, robotics, and automation for mining.
Entrepreneurship and Commercialisation
The Rare Earth Metal and Titanium Theme Park in Bhopal supports startups and technology transfer. Indian Rare Earth Limited leads efforts in commercialising REE technologies developed by national research centres. Public-private partnerships and international collaborations are crucial for scaling innovations.
Future Outlook and Strategic Vision
India’s strategic focus on mining and REE aims to achieve self-reliance by 2047. The launch of India-made semiconductor chips signals readiness for high-tech independence. The country is building a future-ready ecosystem combining exploration, innovation, sustainability, and skilled manpower to lead globally in minerals and materials.
