This paper presents a critical review of underperforming AG/SAG mills based on public domain information comparing design expectations with actual operational performance. …
The specific energies of the SAG and ball mills were determined using AusGrind (Ausenco's in-house software) (Lane, Foggiatto, Bueno and McLean, 2013 and Morrell's ) method. SAG mill specific energy was a function of the inverse of the Axb value, the mill geometry and the mill operating conditions.
3. It has been observed that engineers and consultants have, at times, under estimated the SAG mill specific energy for treating competent ores due to lack of relevant data for comparable benchmark operations, lack of understanding of the test work methods used by various laboratories, and poor use of packages such as JKSimMet.
According to the report from Weir Minerals, comminution in mining consumes up to 1% of total final energy consumption globally — equivalent to the power consumed by 221 million typical U.K. homes. …
2. Trade-off between HPGR and SAG mills. The second case study re-visited the trade-off between SAG and high-pressure grinding rolls (HPGR) at the Tropicana mine by including conveyor power. The below chart shows that the energy efficiency of the HPGR circuit was reduced when the conveying power was included.

Ausgrind is Ausenco's in-house program used for power-based comminution calculations. Proprietary calculations have been developed and reconciled with unit process operation …
However, the SAG mill specific energy is calculated using proprietary models and the specific ball milling specific energy is the differential between the SAG mill and total specific energy requirements. This method acknowledges the limitations of using the P 80 of the transfer size between the SAG mill and the ball mill.
Right angle SAG mill feed (eliminate one pebble recirculation conveyor) Outcomes and achievements. The key features/outcome of the optimized layout are: Coarse ore conveyor length substantially reduced; Reduced pipe rack and piping length; Five (5) set of pumps and two (2) single pumps eliminated; Four (4) pump boxes and two (2) tanks eliminated

Dumont is a large scale, low-grade ultramafic type nickel deposit, averaging 0.27% Ni over a 33 year mine life and is located approximately 60 km northeast of the industrial and mining city of Rouyn-Noranda in northern Quebec, Canada. The project is close to key infrastructure such as roads, rail, power, ports, smelter and airports in the ...
He then compared a range of existing autogenous milling techniques – such as Vertical Roller Mills, High Pressure Grinding Rolls and Autogenous (AG) milling – and their flowsheets to SAG milling to show the potential upside of the different approaches (spoiler alert: AG milling far outperforms SAG milling in terms of operating cost and CO2 ...

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.
The "Phase 1" expansion of the mine, increased the current throughput capacity of 8,000 t/d to 12,000 t/d.
