Recycling Rare Earth Magnet Materials:  Who, Why, Where & How
Mike Guthrie, Vice President of Engineering, Quadrant International

 

Recycling of rare earth magnets was publicly discussed even before NdFeB was introduced, but the replacement of Samarium with the more-abundant Neodymium made those efforts seem unwarranted.  History has repeated itself.  The availability and costs of rare earth materials used in permanent magnets have become unstable due to very large withdrawals from limited sources.  Magnet recycling can help mediate those instabilities and also ease the negative environmental impact of rare-earth mining.  This presentation will present contemporary recycling ideas, processes, and trends and will be beneficial to designers, buyers, producers, fabricators, and users of permanent magnets.
