Back Forty Mine Project | Aquila Resources | Operations

The grinding process reduces the ore to a very fine grain size that is mixed with water to produce a slurry. Next, the slurry (a mixture of solids and liquids) goes into a multi-staged flotation circuit where the mineral-bearing slurry is separated, or floated, from the non-economic material (waste rock).

Grinding Circuits - na.srk

Initially faced with a blend of primary and oxide ore, the circuit achieved in excess of 320tph until the oxide was depleted, leaving only the much harder primary feed. The 2.0MW semi-autogenous grinding (SAG) mill and 3.7MW ball mill was assisted by a 150kW pebble crusher, but the power limitation of the SAG mill resulted in a drop in throughput.
