| Abstract Scope |
The need for rare earth metals in clean energy technologies such as wind turbines and electric vehicles has raised a threat to the supply and spurred researchers to look for sourcing alternatives, with recycling being one of the approaches. Many research investigations have demonstrated the magnet-to-metal approach, in which rare earth metals such as neodymium, praseodymium, dysprosium, and terbium, are leached from magnets by molten metals. These recycled metals can then be involved in the production of new rare earth magnets, providing an environmentally friendly source. This study provides an overview of this method of rare earth magnet recycling, which begins with demagnetization and coating removal. Leaching uses liquid magnesium and bismuth, where distillation is done by a continuous gravity-driven multiple effect thermal system (G-METS). G-METS distillation can potentially improve the efficiency of rare earth metal extraction to help establish a sustainable supply chain for rare earth magnets. |
