The stockpiled ore is reclaimed by the underground feeders and delivered to the grinding section of the concentrator that houses a 28MW semi-autogenous grinding (SAG) mill. Ore is then processed into slurry by the drive ball mills before being delivered to the flotation section of the concentrator plant.

For example, the SAG mill may have 10 MW of power draw available and the two ball mills each of 7.5 MW of power draw available for a total of ratio of 10:15 (1:1.5). The software uses the particular power model (Bond/Barratt, Morrell Mi, etc.) to determine what is the transfer size where the ratio of E SAG to E ball matches the ratio of mill power (1:1.5 in this example).

10/03/2015 In his study it was concluded that the total specific energy of the AG/SAG-ball mill circuit, which was 20.11 kWh/t, was reduced to 11.40 kWh/t by using VRM. A study conducted by Gerold et al. (2012) showed that VRM was able to grind copper and slag with the energy saving of 22.9% and 34.4% respectively compared to conventional grinding circuits.
