water usage. The crushed ore is transferred to a semiautogenous (SAG) mill or ball mill where the ore is further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2). The

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and …
The ore is mined from an open pit, crushed, and fed to ten ball mills. The concentrator is divided into two parallel comminution-flotation sections, so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a …
For each test, 1000 g of the porphyry copper ore was wet ground using a ball mill to 65 wt% passing 200 mesh.
