Abstract

Procédé pour l'enrichissement du charbon. Les fines de charbon sont mélangées en 10 avec une suspension de magnétite préparée en 14 pour être séparées par gravité dans un hydrocyclone 11. Chacun des flux inférieurs et des flux supérieurs est soumis à un flottage inverse 13 et 18 pour récupérer la magnétite Les résidus du flottage inverse sont ensuite épurés par flottage 16 et 20 des fines de charbon. Utilisation de ce procédé pour obtenir des fines de charbon mieux épurées à faible taux de cendres.
