Cellulosic fines and cellulosic fibres are separated from a suspension containing the fines, the fibres and hydrophobic materials by screening the suspension to remove the fibres, and then subjecting the resultant filtrate to dispersed air flotation in the presence of calcium and generally a separation aid to form an upper Reject fraction in which the hydrophobic material is concentrated and a lower Accept fraction in which the cellulosic fines are concentrated.

On sépare les fines et fibres cellulosiques d'une suspension contenant des fines, des fibres et matériaux hydrophobes, d'abord tamisant la suspension pour en retirer les fibres puis en soumettant le filtrat résultant à une flottation avec insufflation d'air dispersée, en présence de calcium et en général d'un agent de séparation, pour former une fraction "rejet" supérieure dans laquelle est concentré le matériau hydrophobe, et une fraction "accepté" inférieure dans laquelle sont concentrées les fines cellulosiques.
