The three primary and secondary crushing stations each crush 5000 tons of ore an hour (t/h) into particles smaller than 150 mm. This material is then conveyed to a 250,000 t surge stockpile prior to being fed into the processing plant. When the ore is fed into the processing plant it first enters the scrubbers, before being sent to wet screening.Web

The smaller ore will go on to the ball grinding mills where they will be further ground down. The larger ore will be routed to a pebble crusher to reduce the size to 1.3 cm (½ in) and will return to the SAG mill stage. The ball mill product is pumped to cyclones which separate out the coarse material with the fine ore.Web
