Abstract
Rare earth materials, in general, and rare earth permanent magnets, in particular, have attracted renewed global interest because of the dominant role these magnets have been projected to play in clean energy sectors in coming decades. In order to augment the primary production, global efforts are currently being pursued either to reclaim the critical rare earth elements from their waste/recyclable materials or devise ways to put them back into the manufacturing supply chain after minimal processing. The presentation will discuss various recycling options/strategies that are currently in progress. Another highlight of the presentation will be discussions on innovative ways to chemically process the waste/manually recovered NdFeB hard disk drive magnets with different chemistries and one-step fabrication of the rare earth metals/alloys from their inexpensive oxide intermediates with relatively less carbon foot print. The presentation will briefly touch upon the feasibility of fabricating SmCo based magnets from the mixed oxides. |
