description The present invention provides a process for dewatering a mineral slurry concentrate and increasing the production of the resulting filter cake consisting essentially of mixing an aqueous mineral slurry concentrate with an effective amount of a nonionic surfactant and an effective amount of a cationic polymer to form a nonionic surfactant and cationic polymer treated aqueous mineral slurry concentrate, and subjecting the treated aqueous mineral slurry concentrate to a liquid water removal process for dewatering the treated aqueous mineral slurry and for increasing the production of a resulting filter cake of the dewatered mineral slurry. An improved mineral slurry concentrate composition and an improved mineral concentrate filter cake is also disclosed.
