Procedure for dewatering a mineral sludge concentrate and for increasing the production of a filter cake |
| abstract |
The present invention provides a process for dewatering a mineral sludge concentrate and for increasing the production of the resulting filter cake, which essentially consists in mixing an aqueous mineral sludge concentrate with an effective amount of a nonionic surfactant and an effective amount of a cationic polymer to form an aqueous mineral sludge concentrate. treated with nonionic, surfactant and cationic polymer, and subjecting the treated mineral sludge concentrate to a process to remove liquid water to dewater the treated aqueous mineral sludge, and to increase the production of a resulting akalter cake of the dewatering mineral sludge. An improved mineral sludge concentrate composition and an improved mineral concentrate filter cake are also described. |
