The invention discloses a method for recycling sintered NdFeB waste. The method comprises the following steps of 1 cleaning, specifically including cleaning greasy dirt and impurities from the surface of the NdFeB waste, drying, and sampling for analyze components; 2, burdening: specifically including filling the waste processed in the step 1 into a vacuum melting furnace, and adding metal La or Ce into the waste; 3, melting: specifically including melting to obtain NdFeB alloy: 4, preparing powder: specifically including grinding into powder with the granularity of 3-5 microns; 5, shaping in a magnetic field: specifically including forming orientation and compression molding in a magnetic field molding press, thus obtaining a pressed blank; and 6 sintering: specifically including sintering at the temperature of 1050-1100 DEG C for 3-5 hours. According to the method, the characteristic that the light rare earth such as La and Ce is more active than weight rare earth, under melting at high temperature, by the reasonable temperature and heat preservation technology, oxides in the waste are fully replaced by the metal La and Ce, so that the material performance is not reduced, meanwhile the price of the metal La and Ce is only one tenth of that of the metal neodymium, and thereby the production cost is reduced.
