摘要: NdFeB permanent magnets are the best available used in many technology applications. However, at their end-of-life (EoL) most of and contained REEs lost during recycling bulk metals. The classified as critical raw materials European Union, from EoL products will reduce criticality contribute to sustainability REE. Various technological routes have been reported, but methods effective for highly concentrated or magnet scrap, which is greatly dependent on expensive pre-dismantling processes. This paper presents various innovative metallurgical solutions REE recovery current industrial practice WEEE recycling, including ferrous scrap shredder residues computer hard disk drives. Both hydrometallurgical combined hydro- pyrometallurgical developed after demagnetization physical upgrading.
