Research on the recovery of NdFeB magnetic material waste

Ndfeb permanent magnet materials are now widely used in defense, aerospace, medical equipment, computers, electronics, robotics and new energy automobile industries due to their superior magnetic properties. The annual global production of Re-Fe-B permanent magnets is more than 300,000 tons, and the manufacturing process will produce magnet chips, cutting chips, grinding chips, ultrafine powder and other waste materials, accounting for 25-35% of the input materials.

Moreover, as time goes by, permanent magnets used as components of various products will gradually expire and become scrapped. For example, in the fields of power machinery, medical equipment, toys, packaging, hardware machinery, aerospace, etc., the Re-Fe-B permanent magnets commonly used include permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment, etc. Therefore, the recycling and reuse of permanent magnets is particularly important.

Developing low-cost, green recycling methods for various elements contained in permanent magnets, especially Rare Earth elements, has become an important technical issue at present, so as to fully utilize the metals in rare earth magnetic material waste and fully recycle the metals in rare earth magnetic materials.

Suzhou KP Chemical Co., Ltd can provide related rare earth raw materials for NdFeB magnets such as Didymium oxide (Praseodymium-Neodymium oxides), Neodymium oxide (Nd₂O₃), Praseodymium oxide (Pr₆O₁₁), Gadolinium oxide (Gd₂O₃), Dysprosium oxide (Dy₂O₃), Holmium oxide (Ho₂O₃), Terbium oxide (Tb₄O₇), Praseodymium neodymium metal, Neodymium metal (Nd), Praseodymium metal (Pr), Terbium metal (Tb), Gadolinium iron alloy, Dysprosium iron alloy and Holmium Iron Alloy. Please contact info@szwww.kpchemmaterial.com or 086-18915544907.
