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
