Abstract
An aqueous beneficiated clay slurry is concentrated from a lower solids content to a higher solids content by evaporating water therefrom by passing the aqueous clay slurry through one or more non-contact evaporative heat exchangers in indirect heat exchange relationship with a hot drying fluid. The driving fluid, that is the heating medium which is passed in indirect heat exchange relationship with the aqueous clay slurry to initiate the evaporation process, comprises a hot liquid, preferably a moderate temperature hot liquid such as hot water having a temperature ranging from about 120.degree. F. to about 200.degree. F.
