Rare　earth　metals　are　one　kind　of　critical　strategic　resources　and　play　irreplaceable　role　in　defense　and　high-technology　area.　As　the　main　global　supplier　of　rare　earth　metals,　long-term　exploitation　and　production　lead　to　serious　problems　including　reserves　decrease,　excessive　energy　consumption　and　heavy　environmental　burden　in　China.　Meanwhile,　the　industrial　wastes　and　end-of-life　wastes　of　sintered　Nd-Fe-B　magnet　accumulated　rapidly,　which　enrich　rare　earth　and　thus　become　one　of　the　important　resources.　As　a　result,　recycling　technology　for　recyclable　sintered　Nd-Fe-B　magnets　has　drawn　considerable　attention　recently.　In　this　paper,　the　formation　and　evaluation　of　recyclable　sintered　Nd-Fe-B　magnets　are　introduced,　and　both　the　industrial　recycling　technology　and　newly-developed　recycling　technology　are　reviewed.　©　2023　Editorial　Office　of　Chinese　Rare　Earths.　All　rights　reserved.
