Abstract

Selon l'invention, pour séparer le plus complètement possible une fraction (R1C) contenant du carbone d'une matière résiduelle (R), résultant par exemple d'une pyrolyse, on sépare d'abord la partie combustible (R1) de la partie non combustible (R2). Ensuite on sépare de la fraction à particules (F) de la partie non combustible (R2) une fraction légère (C) contenant du carbone. Pour obtenir une séparation en continu, on utilise, dans un mode de réalisation préféré, une combinaison comprenant un dispositif (2) servant à la séparation de fils métalliques (D) et un séparateur de parties lourdes (8) monté en aval de ce dispositif. La fraction (R1C) contenant du carbone ainsi obtenue est, de préférence, conduite à la chambre de combustion d'une installation de pyrolyse, pour une autre valorisation.
