| titleOfInvention | Method for recycling rare earth from NdFeB waste |
| abstract | The invention discloses a method for recycling rare earth from NdFeB waste. The method is mainly characterized in that by utilization of oxidability and faint acid performance of hydrogen peroxide, a certain proportion of mixed acid is used for dissolving the NdFeB waste, the NdFeB waste is crushed through an NdFeB hydrogen crushing device, and after acid leaching is finished, N503 is used for extracting the iron element in a leaching agent; and then P507 is used for extracting the single rare earth metal ions, corresponding rare earth metal ions are deposited through oxalic acid and potassium carbonate, and the rare earth metal is further purified. Through scientific purifying design, the defects that in traditional rare earth recycling, energy consumption is high, and acid leaching of oxidation NdFeB is not thorough are overcome; and in the pretreatment process, grinding is not needed, a large amount of dust is prevented from being generated, energy saving and environment friendliness are achieved, and the NdFeB more thoroughly forms the rare earth metal ion through a mixed acid acid leaching method. |
