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.
The power required for the grinding circuit standardised to an F80 of 150 mm and P80 of 75 m is compared to the Bond BWi based power that is theoretically needed to effect comminution from the same size range. ... The highest difference was observed when comparing OMC and MacPhersons method for the Kubaka circuit (-3.7 kWh/t, -13% difference).
A method and a system are disclosed for maintaining optimum throughput in a grinding circuit of the type in which fresh ore is fed to a rod mill and the ground ore from the rod mill, together with the ground ore from a ball mill operated in a reversed circuit, are combined in a pump box and pumped to a cluster of hydrocyclone classifiers.
The development of reliable, laboratory scale SAG testing has opened the door to improved methods for grinding circuit design. The study of ore variability on a blast to blast basis has showed a much higher degree of hardness and throughput variance than was acknowledged when only composite samples were tested in pilot plant facilities or in ...

Kubaka1 and Agnico-Eagle2. Kubaka was a new grassroots project in the Russian Far East while Agnico-Eagle was a plant expansion in north-western Quebec where a new SAG mill was added to an existing ball mill grinding circuit. Both plants were designed using SPI (SAG Power Index) and Bond (Ball Mill Work Index) tests.

The long residence time of the gold within the grinding circuit can cause some of the GRG to become nongravity recoverable due to smearing on to grinding media, mill liners and gangue minerals. This effect is minor as more than 98% of the GRG entering the ball mill remains gravity recoverable after grinding (LaPlante, 2000).
The Kinross Kubaka Project is a gold mine located in the Russian Far East. The grinding circuit, comprised of a 6.1 m diameter x 2.74 m long SAG mill and a 4.1 m diameter x 5.5 m long secondary ball mill in closed circuit with cyclones, was built using SAG Power Index and Bond Ball Mill Work Index testing to determine the grinding energy ...
