    Abstract: A method to inhibit autoprecipitation of aluminum containing compounds in a Bayer process liquor includes adding an effective amount of a polysaccharide to the Bayer process liquor. Polysaccharides which are added in accordance with the present method selected from gum arahic, tamarind gum, gum ghatti and mixtures thereof. Effective addition sites for the autoprecipitation inhibitor are prior to filtering clarified process liquor and subsequent to condensation of caustic soda from spent process liquor.

    Abstract: Materials and a method are provided whereby polymers with least 0.5 mole % of the pendant group or end group containing --Si (OR") 3 (where R" is H, an alkyl group, Na, K, or NH 4 ) are used to control aluminosilicate scaling in an industrial process having an alkaline process stream such as a pulping mill process stream or a high level nuclear waste processing plant. When materials of the present invention are added to the alkaline process stream, they reduce and even completely prevent formation of aluminosilicate scale on equipment surfaces such as evaporator walls and heating surfaces. The present materials are effective at treatment concentrations that make them economically practical.
