摘要 |
<p>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.</p> |
