Following a successful commissioning and start-up we believe that two grinding lines at Las Bambas Per each consisting of one SAG Mill and one Ball Mill (this mill combination is uniquely specific to Las Bambas ore types) are operating at design throughput of close to 140 000 tpd and within the range predicted by DJB from a managed multi-sample geometallurgical testing program (i e no

The ball mill is a 250 kW Marcy-type ball mill that is 8 ft in diameter and 13 ft long The ball mill discharge is pumped to a hydro-cyclone where cyclone underflow reports back to the mill for additional grinding and cyclone overflow is conveyed via gravity to the rougher flotation cells

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
