The　main　difficulty　for　the　recovery　of　Nd-Fe-B　bonded　magnet　wastes　is　how　to　completely　remove　the　epoxy　resins.　In　this　study,　chemical　reaction　and　physical　dissolution　were　combined　to　remove　the　epoxy　resins　by　adding　ammonia-water　and　mixed　organic　solvents.　Ammonia-water　can　react　with　the　epoxy　functional　group　of　epoxy　resin　to　generate　polyols.　Mixed　organic　solvents　of　alcohol,　dimethyl　formamide　(DMF),　and　tetrahydrofuran　(THF)　can　dissolve　the　generated　polyols　and　residual　epoxy　resins.　Under　the　optimum　processing　conditions,　the　epoxy　resins　in　the　waste　magnetic　powders　are　substantially　removed.　The　oxygen　and　carbon　contents　in　the　recycled　magnetic　powder　are　reduced　from　13500　x　10(-6)　to　1600　x　10(-6)　and　from　19500　x　10(-6)　to　2100　x　10(-6)　with　the　reduction　ratio　of　88.1%　and　89.2%,　respectively.　The　recycled　magnetic　powder　presents　improved　magnetic　properties　with　Ms　of　1.306　x　10(-1)　A.m(2)/g,　Mr　of　0.926　x　10(-1)　A.m(2)/g,　Hcj　of　1.170　T,　and　(BH)　max　of　125.732　kJ/m(3),　which　reach　99.8%,　99.4%,　95.9%,　and　96.9%　of　the　original　magnetic　powders,　respectively.　(C)　2021　The　Authors.　Published　by　Elsevier　B.V.
