Recycling and Separation of Critical Rare Earths Elemments
The REEs are the most critical materials with growing demands in advanced modern electronics, communication devices, advanced weapon systems, and sustainable clean technology, catalysts, phosphors, HEV, due to their unique magnetic, optical and catalytic properties. For maintaining present standard of living and providing quality life to future generation, a sustainable production and considerate use of RE must be ensured. Presently scarily only ~1% of REEs being recycled via urban mining. The natural RE ores are very unevenly distributed globally and ~90% of supply is controlled by China. US DoE and EU realized that REs are the MOST CRITICAL and investing heavily in R&D to resolve the crisis. To balance the supply risk, reducing the impact of unsustainable mining and purification, viable recycling of REs from exploitable EOL-EEW, EVs, wind turbine motors, RC-batteries, etc. is very contemporary. New chemical processes and technologies are crucial to recover, separate, and recycle RE in circulation which is both a necessity and opportunity. RE permanent magnets (REPM) forecasted for $50B surging market. In India, the scale-up potential is quite viable as 1.5 B internet users with ~1.2 B phones by 2040, yearly import of 15M PCs with 20% growth. GoI’s thrust on reviving automobile industry, EVs, low-C economy, and renewable clean energy will provide long-term feedstock for urban mining of essential metals. We must realize the untapped potentials of urban mining from EEW wastes dumped in landfills with deleterious environmental effects. RE recycling is a strategic necessity & opportunity for Atmanirbhar Bharat & sustainable economy.
