ABSTRACT:
The present invention relates to dewatering of an aqueous slurry of calcium carbonate. More particularly, the present invention relates to the use of non-ionic surfactants in dewatering aqueous slurries of an aragonitic precipitated calcium carbonate. Calcium carbonate slurries dewatered using the non-ionic surfactants of the present invention have higher weight percent solids, decreased dispersant demand, and result in higher productivity.
