Abstract: Methods and compositions for improving performance of flocculants in an industrial production process. Methods include pH triggered cross-linking reaction between a flocculating agent, such as dextran, and a composition comprising a boronic acid-containing polymer. The pH trigger can be provided by a fluid having a pH of 8 or more. The production process can be a Bayer Process and the fluid is caustic liquor or slurry in the fluid circuit of the Bayer, wherein the reaction time is reduced over conventional methods and the cross-linked dextran composition effectuates improved flocculation of the trihydrate particles.

Abstract: The invention provides methods and compositions for freeze conditioning particulating materials. The invention includes the use of the combination of crude glycerin with flowback or produced water. This combination prevents unwanted agglomeration when frozen. This combination also is non-corrosive and best of all facilitates the safe clean recycling of what would otherwise be unwanted dangerous waste material.
