ABSTRACT:
A method for reducing the relative viscosity of a phosphate rock slurry during a grinding process in a phosphoric acid production facility is described. The method includes the steps of adding an effective amount of a sulfonated acrylamide or acrylic acid polymer having a molecular weight of from 500 to 100,000 and being selected from the group consisting of sulfonated polymers of acrylic acid/acrylamide copolymers and the copolymerization products of acrylic acid, acrylamide and 2-acrylamido-2-methylpropyl sulfonic acid.
