| titleOfInvention |
Process for dewatering mineral tailings by the treatment of these tailings with at least one anionic polymer and at least one cationic polymer |
| abstract |
The invention relates to a process of dewatering a suspension comprising particulate solids dispersed in an aqueous liquid, said particulate solids comprise clay and mineral particles of size below 50 μιτι, 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 anionic polymer and at least one cationic polymer to the suspension before, during or after step (a); (c) dewatering the treated suspension obtained after having conducted steps (a) and (b), in which the kinetic energy stage is a shearing stage and/or application of ultrasonic energy to the suspension. |
