Beschreibung
Zusammenfassung:	The invention pertains to a process for separating mixtures of solids based on their densities. The present invention also relates to the use of a separating liquid (L) for separating plastic solids from metal-containing solids based on their densities, wherein the separating liquid (L) has a density d3 such that 1.5 < d3 < 2.0; wherein the solids have a particle size ranging from 0.1 to 100 mm. The separating liquid (L) is preferably a fluorinated fluid. L'invention concerne un procédé de séparation de mélanges de solides sur la base de leurs densités. La présente invention concerne également l'utilisation d'un liquide de séparation (L) pour séparer des solides plastiques de solides contenant du métal sur la base de leurs densités, le liquide de séparation (L) ayant une densité d3 telle que 1,5 < d3 < 2,0 ; les solides ayant une taille de particule allant de 0,1 à 100 mm. Le liquide de séparation (L) est de préférence un fluide fluoré.
