The SAG mill is one of the largest volumetric capacity SAG mills in the world and represented the first 40 ft. SAG mill in Peru (Garcia & Villanueva, 2013 [1]). Antapaccay's flow sheet is shown in Figure 1 below. Figure 2 shows the copper concentrator photographed after commissioning. Figure 1 Antapaccay's flow sheet
SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill.
The rougher bulk concentrate contains 4% copper with 75% recovery. After recleaning, the final copper con-centrate produced contains at least 20% copper with 85% recovery. The plant within the Tominskii MPE produces 28 million t of porphyry copper ore per year, where the initial content of copper in the ores is 0.4%.

A SAG Mill is processing Copper Ore. Grinding Balls [] Grinding Balls are consumable items that can be placed in the top-right slot of the SAG Mill's GUI. After one is placed into its dedicated slot, the Grinding Ball itself will be consumed upon beginning the first applicable processing job. Its effect continues to last until its durability ...
energy required which in this case was to grind the ore represented by the samples, from a feed size F80 of 152 mm to 80% passing 1.7 mm, and a simple adjustment procedure in case the SAG product size needed to be adjusted. Bond rod and ball mill work indices are readily converted to pinion energy for rod and ball mills but not for SAG mills.

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 Kamoa-Kakula copper ore has A×b value of 21.32: only 1.5% ore in the JK database has such high hardness. As for hard ore, multiple trade-off studies have reported the performance of HPGR- versus SAG-based processes, with energy savings of between 11% and 32% (Ballantyne et al., 2018).
