Abstract

La présente invention concerne un procédé de déshydratation d'une suspension comprenant des solides particulaires dispersés dans un liquide aqueux, lesdits solides particulaires comprenant des particules d'argile et de minéraux d'une taille inférieure à 50 µm, ce procédé comprenant les étapes de (a) soumission de la suspension à une phase d'énergie cinétique pour produire une suspension modifiée; (b) addition de particules polymères solides à la suspension, l'étape (a) pouvant être appliquée avant, pendant ou après l'étape (b); déshydratation de la suspension modifiée obtenue après application des étapes (a) et (b), la phase d'énergie cinétique étant une phase de cisaillement et/ou l'application d'une énergie ultrasonore à la suspension.
