The effect of slurry density on breakage parameters of ...

Abstract Batch wet grinding of 20 × 30 mesh feeds of quartz and copper ore in a laboratory ball mill gave first-order or non-first 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 first-order manner, with normalized primary breakage distributions.

Determining milling parameters of a pear-shaped ball mill ...

Grinding tests were conducted on an oxidized copper-cobalt ore using a pear-shaped ball mill. Twelve mono-sized ore fractions were prepared and wet ground batchwise. The mill was run for 0.5 to 30 min intervals. The shortest interval provided data more closely related to the breakage function (B) because less secondary breakage was hypothesized.
