Finding the Ore Liberation Size For Gravity Circuits: Sizing …
In processing our local ore with the MBMM jaw crusher, hammer mill and shaker table, we get a p80 of ~30-50 mesh (80% passing 30 or 50 mesh sieve screen), depending upon the slot size in the hammer mill screen. Results show nearly 50% of the gold recovered was at <100 mesh, and a surprising amount of gold was at <325 mesh.

Ball Mill (Ball Mills Explained)
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
