The BGM comminution circuit includes a primary crushing stage with a gyratory crusher and a two grinding circuits using a Semi-Autogenous Grinding (SAG) mill and a ball mill. The SAG mill circuit also includes

In the Aitik copper mine a raised specific charge from 0.9 to 1.3 kg/m 3 gave rise to an increase in the throughput by nearly 7% due to more fines produced and shorter grinding time achieved [28]. Similarly, a high specific charge from 2 to 3.0 kg/m 3 resulted in an increase in the mill throughput by 20–40% [29] .

The HPGR-ball mill circuit when grinding to 75 um compared to 160 um used an extra 4.6 kWh/mt, but for the SABC circuit it only used an extra 1.8 kWh/mt. The reported SABC circuit power for the 160 μm grind size was based on actual site data. JKSimMet was used to fit a model to site DCS data.
