• Previous bottleneck was accumulation of harder rock

• Installation of the SABC circuit allows for larger discharge ports to be fitted in

the SAG mill

• Hard ore particles pass on to a cone crusher – reduced from 50mm to <

10mm

• Rejoins the SAG feed where it is able to pass straight through to the Ball mill

without accumulation

• Allows for reduced power consumption in breaking this harder material while

increasing throughput.
