  • Estimated Water Requirements for the Conventional

    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
