Sag Milling | PDF | Mill (Grinding) | Mining Scribd
Typically, a SAG mill based circuit (P80 of 106 to 150 um) has media costs of around A1/t. Providing the ore is amenable, the use of primary autogenous milling can reduce this cost by 30 to 40%. Autogenous milling is typically practiced in association with pebble crushing to improve circuit power efficiency.
