摘要: A method for isolating a humic substance from alumina process liquor is provided herein. Separate from or within the method, bauxite is processed to form the alumina process liquor. The method includes providing a diallyldimethylammonium chloride-containing polymer. The method further includes providing an amine-containing polymer. The method further includes combining the diallyl dimethyl ammonium chloride, the amine-containing polymer, and the alumina process liquor, to isolate the humic substance from the alumina process liquor.

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 a liquid-solid separation and filtering the liquid from the solid. The method may be applied in mining operations for the filtering of mining slurries.
