Abstract

Procédé de récupération d’aimants permanents de type NdFeB à partir de déchets d’équipements électriques et électroniques, comprenant les étapes successives suivantes :- soumettre des aimants permanents désaimantés à une première séparation magnétique à tambour 400 G, - récupérer une première phase magnétique (1FM), - soumettre la première phase magnétique (1FM) à une première séparation magnétique sur un séparateur Overband, de manière qu’une deuxième phase non magnétique (2FNM) issue de la première séparation magnétique Overband soit enrichie en aimants désaimantés, - récupérer la deuxième phase non magnétique (2FNM).
