Disclosed is a process of dewatering a suspension comprising particulate solids dispersed in an aqueous liquid, the particulate solids comprises clay and mineral particles of size below 50µm, which process comprises the steps of (a) subjecting the suspension to a kinetic energy stage to produce a modified suspension; (b) addition of at least one surfactant and at least one polymer to the suspension during and/or after step (a); (c) dewatering the treated suspension obtained after having conducted steps (a) and (b). |
