The present invention provides a method for separation of fine particles in a bimodal (two component) dense medium. In accordance with the present invention, the dense medium comprises ferromagnetic particles that have a relative density range from about 4.0 to 7.0 suspended in water and are characterized by a bimodal size distribution. Such a medium exhibits high stability and favourable rheological properties. The use of such a bimodal magnetite dense medium in cleaning fine coal in a dense medium cyclone or dynamic dense medium separator results in optimum separation efficiency when the medium contains approximately 20-40 % fine and 60-80 % coarse magnetite, and when the size ratio of coarse-to-fine magnetite is in the range of 5 to 10.

L'invention concerne un procédé de séparation pour fines particules en milieu dense bimodal (à deux constituants). On décrit un milieu dense qui comprend des particules ferromagnétiques ayant une plage de densité relative comprise environ entre 4 et 7, en suspension dans l'eau et caracterisées par une distribution bimodale de taille. Ce milieu offre une haute stabilité et des propriétés rhéologiques favorables. En utilisant un tel milieu dense à magnétite de type bimodal pour le nettoyage des fines de charbon dans un cyclone en milieu dense ou un séparateur dynamique en milieu dense, on obtient une efficacité de séparation optimale lorsque ledit milieu contient environ de 20 à 40 % de magnétite fine et environ de 60 à 80 % de magnétite brute, et lorsque le rapport de taille brute/fine de la magnétite se situe dans une plage comprise entre 5 et 10.
