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.

Alkaline spray-on cleaners that can be delivered by pump or pressurized gas aerosol spray have been made with reduced choking mists are disclosed. The cleaning composition comprises the use of anti-mist components consisting of large anionic copolymer comprised of acrylamide and AMPS (acrylamide-sodium 2-acrylamido-2-methylpropane sulfonate), and polyethylene oxide polymers that create non-Newtonian solutions. The composition also includes a surfactant, and a source of alkalinity.
