autogenous grinding (ABCtype) circuit. Autogenous milling is generally considered as being one of the higher risk milling circuits. This is mainly due to the fact that the ore, which is utilised as the grinding media, could be variable in terms of hardness and mineralogy / geology. Nevertheless, it is a very popular route as the cost benefits, more

The circuit operates with a semiautogenous grinding (SAG) – ball mill circuit, feeding a bank of OK200 rougher cells. Rougher concentrate is reground in an IsaMill prior to entering a cleaner circuit consisting of three stages of cleaning and one stage of cleaner scavenging. The concentrate typically assaying 24 per cent Cu and 6 7 g/t Au is

Secondary grinding efficiency (as measured by kWh per ton finer than 75 microns or Work Index), was improved substantially by reducing the pebble size to 20/28mm. The process as a whole was optimised when crushed rock coarser than 4 mm was recycled to primary mill, as the small pebbles were most efficient with "sand".
