| titleOfInvention | Method for treating aliminum hydroxide |
| abstract | A method for treating amorphous aluminum hydroxide to reduce the water content of a sludge thereof without varying the properties of the hydroxide and remove various metallic compounds and silicates therefrom, wherein the amorphous aluminum hydroxide is pulverized and subjected to instantaneous evaporation of water, thereby reducing the water content to a level equal to that for crystalline aluminum hydroxide while maintaining the amorphous state and the solubility thereof in caustic alkalies. Further, when the finely divided and dried amorphous aluminum hydroxide contains metallic compounds and organic polymeric compounds as impurities, the amorphous aluminum hydroxide may be dissolved in an aqueous caustic alkali solution until the aluminum concentration becomes supersaturated, thereby precipitating the compounds, which are then removed by solid-liquid separation. Still further, when the crystalline aluminum hydroxide, which has been precipitated from an aqueous caustic alkali solution and recovered by solid-liquid separation, contains silicates, it may be dissolved in an aqueous sulfuric acid solution and kept at 60 °C or above and pH 1 to 2 to convert the silicates to insoluble polymers, which are then cooled and removed by solid-liquid separation. |
