Yun et al. studied REE extraction from spent NiMH batteries using acid leaching and extraction with a primary amine extractant of N1923. Results showed that 99.98% of REEs were extracted after a five-stage counter-current extraction followed by HCl stripping and oxalic precipitation.
Based on revenue potential per unit mass, didymium (Nd + Pr) metal and high-grade nickel metal are the two most valuable co-products which are recovered via recycling of the batteries. Despite comprising less than 1% of the total recovered materials by mass, didymium generates over 14% of the total potential revenue from all products recovered.
Valorization of waste NiMH battery through recovery of critical rare earth metal: a simple recycling process for the circular economy
This review explores the potential of separating and recycling rare earth elements (REEs) from different energy conversion systems, such as wind turbines, electric vehicles batteries, or lighting devices. The REEs include 17 elements (with global production of 242 kilometric tons in 2020) that can be found abundantly in nature.
