Title (EN) CONCENTRATING GRAPHITE PARTICLES BY AGGLOMERATION WITH HYDROPHOBIC MAGNETIC PARTICLES
(FR) CONCENTRATION DE PARTICULES DE GRAPHITE PAR AGGLOMÉRATION AVEC DES PARTICULES MAGNÉTIQUES HYDROPHOBES
Abstract:
(EN) A process for concentrating graphite particles comprising a) providing a feedstock which contains the graphite particles and an undesired material, b) adding hydrophobic magnetic particles to the feedstock which results in a loaded feedstock containing agglomerates of the magnetic particles and the graphite particles, and c) separating the agglomerates from the loaded feedstock by a magnetic field which results in isolated agglomerates.
(FR) L'invention concerne un procédé de concentration de particules de graphite comprenant a) la fourniture d'une matière première qui contient les particules de graphite et un matériau indésirable, b) l'ajout de particules magnétiques hydrophobes à la matière première, ce qui produit une matière première chargée contenant des agglomérats des particules magnétiques et des particules de graphite, et c) la séparation des agglomérats de la matière première chargée par un champ magnétique, ce qui produit des agglomérats isolés.
