    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.
