Bulk　sintered　Nd-Fe-B　waste　magnets　come　mainly　from　machining　scraps　and　magnets　dissembled　from　waste　apparatus.　These　waste　magnets　keep　the　similar　chemical　composition　and　microstructure　of　virgin　sintered　Nd-Fe-B　magnet.　Therefore,　wet-process　metallurgy　method,　which　involves　complicated　recycling　procedure,　high　recycling　cost　and　potential　environmental　pollution,　is　not　fit　for　bulk　sintered　Nd-Fe-B　waste　magnets.　In　recent　years,　hydrogen　treatment　technology　has　been　developed　to　recycle　the　waste　magnets　in　the　way　of　short　route,　low　cost　and　high　efficiency.　In　present　paper,　the　mechanism,　technical　route　and　current　progress　of　the　hydrogen　treatment　technology　for　waste　magnets　recycling　were　introduced.　©　2016,　Editorial　Office　of　＂Chinese　Rare　Earths＂.　All　right　reserved.
