The designation of seven premier academic institutions—including four Indian Institutes of Technology (IITs)—as Centres of Excellence (CoEs) under the National Critical Minerals Mission (NCMM) represents strategic government decision to concentrate rare earth R&D capacity within India’s top scientific institutions. These CoEs function as hubs within coordinated “hub-and-spoke” models, bringing together researcher networks, laboratory facilities, and industry partnerships to accelerate innovation and technology translation.
IIT-Led Research Ecosystem:
The four IIT Centres of Excellence—IIT Bombay, IIT Hyderabad, IIT (ISM) Dhanbad, and IIT Roorkee—collectively represent India’s most advanced mineral science capabilities. Each institution brings distinct expertise complementing national rare earth strategy.
IIT (ISM) Dhanbad has emerged as the leading academic voice in rare earth research. Professor Dhruva Kumar Singh, highlighting “significant strides made in India’s R&D ecosystem for rare earths,” has emphasized the importance of building an integrated REE value chain within India. His research group focuses on rare earth beneficiation, mineral exploration, and integrated processing flowsheet development. Professor Singh’s statement encapsulates the institutional priority: “The technologies exist and are ready for scale-up—what is now needed is stronger industry uptake, government support, and collaboration with academia to commercialize these innovations and strengthen India’s strategic self-reliance.”
This framing—technology readiness versus scaling and commercialization—defines India’s rare earth challenge. R&D has advanced to pilot and demonstration scale across multiple pathways; translating laboratory success to industrial production at competitive costs remains the critical gap IIT research is addressing.
IIT Bombay, India’s top-ranked engineering institution, brings strengths in materials engineering, chemical process design, and industrial-scale manufacturing. The institute’s researchers are developing advanced beneficiation techniques for low-grade and complex rare earth ores—addressing India’s specific mineralogical challenges. IIT Bombay’s Process Engineering Laboratory has initiated projects on rare earth separation using advanced crystallization, selective precipitation, and membrane-based techniques. The institute also operates collaboration with industry partners including specialty chemical manufacturers exploring commercial pathways.
IIT Hyderabad, located within India’s thriving biotech and materials science ecosystem, focuses on bioprocess engineering applied to rare earth extraction. Researchers are exploring genetically-engineered microbes for selective rare earth bioleaching, enzyme-based separation techniques, and biosorption methodologies. The institute’s proximity to materials science and biotechnology clusters creates unique opportunities for bio-inspired rare earth technologies. IIT Hyderabad is also integrating nanotechnology approaches—producing nanosize rare earth particles with enhanced properties for advanced applications.
IIT Roorkee, India’s oldest technical institute, contributes expertise in hydrometallurgy and applied chemistry. Researchers are developing advanced solvent extraction methodologies, studying thermodynamic properties of rare earth-solvent systems, and optimizing separation sequences to reduce chemical consumption and waste generation. The institute’s strong industrial partnerships with chemical manufacturers facilitate rapid technology transfer.
Supporting CSIR Institutions:
Beyond IITs, three CSIR institutions designated as CoEs bring complementary expertise:
CSIR-IMMT Bhubaneswar provides materials science and processing expertise, particularly for biomimetic extraction and value-added product development.
CSIR-NML Jamshedpur contributes strategic metals research, recycling technologies, and secondary resource utilization expertise.
NFTDC (Centre for Materials for Electronics Technology) Hyderabad specializes in materials characterization, advanced analytical techniques, and defense-sector materials applications—bridging rare earth technologies with military hardware requirements.
Research Focus Areas:
The CoEs have organized research around five priority areas aligned with NCMM objectives:
- Exploration and Resource Characterization: Developing advanced geophysical and geochemical mapping techniques to identify rare earth deposits, assess reserve quality, and predict processing requirements. IIT Dhanbad’s mineral exploration work and NGRI collaboration exemplify this focus.
- Beneficiation and Concentration: Creating low-cost techniques to concentrate rare earths from low-grade ores before chemical processing. This reduces downstream processing burden and improves economics.
- Advanced Extraction Methodologies: Developing hydrometallurgical (aqueous chemistry-based), pyrometallurgical (high-temperature), and bio-based processes tailored to India’s ore types and environmental standards.
- Selective Separation and Purification: Creating processes to isolate specific rare earth elements (neodymium, dysprosium, terbium) from mixed concentrates with minimal waste.
- Secondary Resource Utilization and Recycling: Maximizing rare earth recovery from e-waste, battery scrap, industrial byproducts, and red mud.
Patent and Innovation Pipeline:
The NCMM targets 1,000 patents across the critical minerals value chain by 2030. IIT research groups are actively filing patents on novel processes, materials, and applications. Patent filings have increased substantially since mission launch in 2024-25, reflecting intensified research output. Notable patent areas include:
- Bioleaching processes optimized for Indian ore characteristics
- Selective solvent extraction methodologies reducing chemical waste
- Nanosize rare earth oxide production techniques
- Recycling processes for specific rare earth magnets and phosphor applications
- Value-added ceramic, coating, and optical material development
University-Industry Collaboration Models:
IIT CoEs are pioneering structured university-industry partnerships enabling technology translation. IIT Bombay researchers collaborate directly with IREL on processing optimization. IIT Dhanbad engages with both CSIR-NML and private companies on beneficiation techniques. IIT Hyderabad partnerships extend to biotech firms exploring bioprocessing applications.
These collaborations function through dual mechanisms: sponsored research projects funded by industry partners, and internship/postdoctoral placements enabling student engagement with real-world problems. This model accelerates technology transfer while providing students with industry exposure.
Capacity Building and Workforce Development:
A critical NCMM objective is building India’s rare earth scientist and engineer workforce. IIT CoEs have established rare earth science and engineering programs, including dedicated postgraduate specializations. The institutes are recruiting senior researchers with international rare earth experience and offering competitive postdoctoral positions to retain talent.
This workforce development addresses India’s significant challenge: despite large R&D community, few scientists possess deep rare earth processing expertise—much expertise resides in China or Western companies. IIT programs are systematically building this expertise base through structured education, international collaboration, and industry engagement.
International Research Partnerships:
IIT researchers are engaging with leading global rare earth research groups. IIT Bombay faculty have collaborative arrangements with universities in Germany, Sweden, and Australia on advanced separation techniques. IIT Dhanbad researchers present regularly at international rare earth conferences, building India’s profile in global scientific community.
These international partnerships serve dual purposes: importing advanced methodologies and global best practices into India, and positioning Indian researchers within international networks for future technology transfer and collaboration.
Challenges and Future Trajectory:
IIT CoEs face coordination challenges in hub-and-spoke model—ensuring effective communication and resource sharing across geographically dispersed institutions. Funding availability for long-term R&D projects (5-10 years) remains constrained. Private sector engagement in university research remains lower in India than in developed economies.
However, the trajectory is clear: structured academic research through CoEs is transitioning from generic materials science into focused rare earth innovation addressing specific Indian requirements. The next 3-5 years will test whether academic research translates into commercial technologies and production scale-up.
