Single Stage SAG Mill. Using SAG instead of AG increases the capacity as well as application range, but will also increase wear costs and still be dependent on "natural" product size being close to the desired. Common circuit in the US and Canada . Single stage SAG mill circuit [image: (135625)]
Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between and kWh per ton of energy to reduce the particle size.

The average gold head grade over the LOM is g/t Au. The mill throughput strategy in 2015 to 2019 is based on saprolite/fresh rock blend. Gold recovery is nominally % for saprolite and % for fresh rock. Total of tonnes of ore processed. Fresh Rock is crushed prior to the single stage SAG mill grinding section followed by
Mar 07, 2013· difference between sag mill and ball mill | Solution for ore mining. ... Ball scats from a singlestage SAG mill and Crusher feed belt ... SAG mill design,SAG mill for sale for the ball milling process. The SAG ball mill has been simulated by discrete event simulation (DES) ...
Dec 21, 2012· design. The design targets a relatively coarse grind size of 106 microns and comprises a comminution circuit with primary crushing followed by a single stage SAG Mill with a recycle pebble crusher. Gold extraction is then achieved through a standard CIL circuit followed by elution, electrowinning and smelting. For personal use only
Jerritt Canyon Freeport Gold Original Grinding Circuits were single stage SAG mills followed by Ball mills. Because the initial Oxide ores were "Jasperoid " and had higher than expected work index, the mill capacity was less than 50% of design.
AG/SAG mills for a given feed size distribution and feed rate (Morrell and Morrison, 1996). Hence when using JKSimMet in a design situation, the dimensions of the AG/SAG mill are adjusted until the load in the mill reaches 25 % by volume when fed at the required feed rate. The model predicts the
The properties of Minera Yanacocha ('Yanacocha') are located 48 kilometres north of the city of Cajamarca, in Peru. Yanacocha began production in 1993 and Newmont holds a % interest in Yanacocha. Yanacocha has four leach pads, three gold recovery circuits and a new milling circuit (single stage SAG mill,
