Process For Dewatering A Mineral Slurry Concentrate And Increasing The Production Of A Filter Cake
US Patent:
7824553, Nov 2, 2010
Filed:
Jul 24, 2007
Appl. No.:
11/880716
Inventors:
Keith C. Hovland - Wadsworth OH, US

Assignee:
Neo Solutions, Inc. - Beaver PA
International Classification:
B01D 37/03
US Classification:
210727, 210728, 210734, 210735, 210778
Abstract:
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.
