Comparison of ore hardness measurements for grinding mill ...

Hardest measurements were used to allow any blend of feed to be treated at design t/h. A total of 9 kWh/t of grinding energy was indicated and this could be provided either in a single stage SAG mill to produce the P80 200 micron product, or a two stage circuit with equal power on the SAG and ball mills using the design Bond Wi of 11.5 kWh/t.
