Abstract
Provided is a method for manufacturing an abrasive agent including a dispersant and also including cerium oxide as a main abrasive material component. The method involves: a step for recovering an abrasive agent component by salting out a spent abrasive material slurry by using a cation of an element of the first Group or second Group with an ionic radius of 80 pm to 160 pm in six-coordinate conversion, and solid-liquid separating the cerium oxide by coagulation and sedimentation; and a step for adding a dispersant including an anionic polymer to the abrasive agent component after the recovery.
