New scientific publication highlights N9VE’s work on rare earths recovery from end-of-life NdFeB magnets
N9VE is pleased to announce the publication of a new scientific article in Minerals Engineering, entitled “Rare earth elements recovery from end-of-life NdFeB magnets towards new applications using design of experiments for leaching process”.
The article presents a study on the recovery of rare earths from end-of-life NdFeB permanent magnets through a hydrometallurgical process based on acid leaching. The work combines Design of Experiments with exploratory machine learning tools to support process optimization and improve the understanding of the main factors affecting rare earth element recovery.
The results highlight the potential of NdFeB magnet recycling as an efficient route for recovering critical elements such as neodymium and praseodymium, contributing to the development of more circular and sustainable solutions within the critical raw materials value chain.
This publication reinforces N9VE’s commitment to advancing innovative technologies for the recycling and valorisation of strategic materials, supporting the transition towards a more resilient and sustainable European supply chain.
N9VE would like to thank the Centre of Biological Engineering of the University of Minho and the Centre of Chemistry of the University of Minho for their collaboration in this work, as well as all co-authors involved.
This work was funded under the N9VE.REEnew project, financed under COMPETE2030, PORTUGAL2030 and the European Union through the European Regional Development Fund (ERDF), focusing on the scale-up of circular and sustainable processes for rare earths recovery.
