Abstract
La présente invention concerne un procédé de séparation d'au moins un premier matériau d'un mélange comprenant cedit premier matériau et au moins un deuxième matériau qui consiste à mettre en contact le mélange comprenant au moins un premier matériau et au moins un deuxième matériau avec au moins une particule magnétique, ou mettre en contact le mélange comprenant au moins un premier matériau et au moins un deuxième matériau avec au moins une particule magnétique et au moins une substance de modification de surface en même temps, mettre en contact le mélange de l'étape (A) avec au moins une substance de modification de surface, si cela n'a pas été réalisé lors de l'étape (A), de façon que ledit premier matériau, ladite substance de modification de surface et ladite particule magnétique s'attachent les uns aux autres, et séparer le produit de l'ajout en appliquant un champ magnétique.
