Abstract: The process of the present invention includes obtaining a feed material having an initial median particle size A solution of a polycarboxylate dispersant in water is formed, then the feed material is added to the solution to form a slurry The slurry is wet-ground to reduce the median particle size of the feed material Optionally, the total amount of polycarboxylate dispersant is divided into a plurality of doses that are added periodically over the total grinding time
