The two installed mills include a semi-autogenous (SAG) mill measuring 10.4 x 6.1 m with a drive output of 15 MW; and a ball mill rated at 18 MW. The SAG mill reduces ore fragments with a maximum size of 250 mm (P80 = 152 mm) down to 2 mm, and the ball mill reduces the SAG mill product to about 74 µm. Grinding is followed by flotation.
