Abstract

La présente invention concerne un procédé pour séparer des mélanges de particules en une première fraction et une deuxième fraction, la conductivité électrique des particules de la première fraction étant supérieure à celle de la deuxième fraction. L'invention a pour objet de proposer un procédé au moyen duquel un mélange de particules à grains fins, notamment des déchets électroniques de modules photovoltaïques ou de batteries lithium-ion, peut subir une séparation de manière économique. A cet effet, le procédé consiste à : a) fournir un mélange de particules fluidisé contenant deux fractions particulaires de conductivités électriques différentes; b) ioniser dans un même sens de l'air au moyen d'au moins une électrode à effet couronne qui entoure l'air à ioniser; c) mélanger l'air ionisé au mélange de particules fluidisé pour obtenir un mélange de particules fluidisé ionisé dans un même sens; d) faire se déposer des particules de la deuxième fraction à partir du mélange de particules fluidisé ionisé sur une électrode de captage qui est en mouvement par rapport au mélange de particules fluidisé ionisé et qui est mise à la terre ou a une charge opposée à celle de l'électrode à effet couronne; e) prélever les particules qui adhère à l'électrode de captage, en tant que deuxième fraction; f) obtenir la première fraction composée de particules du mélange de particules fluidisé ionisé, qui n'adhèrent pas à l'électrode de captage.
