Abstract

L'invention concerne un procédé de nettoyage et de déshydratation de matières particulaires hydrophobes. Le procédé est effectué en deux étapes : 1) agglomération des particules hydrophobes dans un mélange premier liquide hydrophobe/aqueux, suivie par 2) dispersion des agglomérats dans un second liquide hydrophobe pour libérer l'eau piégée à l'intérieur des agglomérats conjointement avec les particules hydrophiles entraînées.
