A process for recycling an electronic scrap material comprising a metal provided on a polymeric substrate, which method comprises: milling flaked electronic scrap material with a bead impact material in the presence of water to produce flakes of cleaned polymeric substrate; adding water to the milled material and separating the flakes of cleaned polymeric substrate from metal-containing material; dewatering and drying the flakes of cleaned polymeric substrate; and treating the metal-containing material to recover the metal.

L'invention concerne un procédé de recyclage des ferrailles électroniques constituées d'un métal déposé sur un substrat polymère. Ledit procédé consiste : à broyer les ferrailles électroniques réduits en flocons au moyen d'un matériau d'impact du type billes, en présence d'eau, de manière à produire des flocons de substrat polymère nettoyé; à ajouter de l'eau aux ferrailles broyées et à séparer les flocons de substrat polymère nettoyé du matériau renfermant le métal ; à déshydrater et à sécher les flocons de substrat polymère nettoyé ; et à traiter le matériau renfermant le métal pour récupérer le métal.
