Background technique

NdFeB waste is the main type of rare earth permanent magnet waste at present. NdFeB waste is generally powdery, granular, massive, muddy, some with high water content, some with less water content, and some soaked in liquid Among them, some samples show different colors and odors, and most samples have low volatile components. The recovery of NdFeB waste is more convenient than direct crushing of ore to obtain rare earth resources, because the content of rare earth in NdFeB waste is much higher than that of ore.

In addition, the waste generated after the processing of NdFeB products is probably more generated in the following five situations: (1) Various single raw material losses generated during the pretreatment of raw materials such as metal neodymium, pure iron, boron iron, metal Dy et al. (2) Severely oxidized neodymium iron boron waste produced in some processes, such as oxide scale produced in the smelting and ingot casting process, ultra-fine powder produced in the pulverizing process, and magnetic powder that ignites due to exposure to the air in this process, The alloy powder scattered during magnetic field forming is the grinding powder in the machining process. (3) Some slightly oxidized neodymium iron boron bulk materials produced during the sintering process. (4) A large amount of scraps produced in the machining process. This process is the unit that produces the largest waste in the entire NdFeB production process. (5) Surface treatment of unqualified products such as copper plating, nickel plating, and zinc plating.
