| Abstract Scope |
Permanent magnets are crucial components for several key industries that contributing to the green transition such as wind turbines and electrical vehicles as well as consumer electronics such as computers, smartphones and household appliances. These magnets must be recycled for a sustainable and secure supply chain of REEs for the current and future applications due to raw material availability issues and its volatile market.
Various techniques have been investigated for the recycling of EoL permanent magnets. These methods include not only direct reuse of the magnet, or reprocessing after hydrogen decrepitation, but also pyrometallurgical and hydrometallurgical processes to recover the raw materials. This multifaceted approach to recycling operations reflects the complex nature of NdFeB magnets and points out that the processing challenges have not yet been overcome. Each of the techniques described has distinct advantages and disadvantages, that require a thorough evaluation of the potential challenges of their industrial application. |
