fully autogenous mills of 10.4m diameter by 3.5m long (34 x 11.5 ft.), equipped with 6000 kW motors. The mills operate in closed circuit with single deck screens fitted with nominally 1.7mm apertures (1.4 x 25mm slots when new). The typical power draw for each mill is in the region of 5200kW with a feed rate of about
