PROCESS FOR FILTRATION ENHANCEMENT OF AQUEOUS DISPERSIONS
摘要
A method for enhancing filtration performance in separating solids from liquids in an aqueous dispersion comprising a solids phase and a liquid phase in a two step process having a physical separation step and a filtration step comprising adding at least one filtration aid promoter and at least one synthetic polymer to the aqueous dispersion during and/or before the physical separation step resulting in concentrate and filtering the concentrate. The method may be applied in mining operations for dewatering mining slurry. Also, a composition applied in such method comprising at least one filtration aid promoter and at least one synthetic polymer. The filtration aid promoter comprises natural polymers, semi-natural polymers, coagulants and combinations thereof.
