Abstract Batch wet grinding of 20 30 mesh feeds of quartz and copper ore in a laboratory ball mill gave firstorder or nonfirst breakage of this size depending on conditions, with acceleration of breakage rate occurring for lower slurry density and deceleration at higher. Smaller sizes in the slurry appeared to break in a firstorder manner, with normalized primary breakage distributions.
