Optimum filling ratio. U= (volume of powder in the mill)/ (volume of voids in the charge): between 60% and. 110%, optimum around 90%. In practical terms, material level should equal ball level in the first compartment. In practical terms, material level should be higher than ball level in the second.

CIL (Carbon In Leach) is the carbon leaching method for gold extraction. Normally the CIL process can concentrate gold from g/t in ore to 2000 to 6000 g/t on carbon. CIL gold process is suitable for beneficiating oxidized gold ore with low sulfur and mud content. It is characterized by low cost, short infrastructure construction time and few production links.

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 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
