Sulfide ore treatment A two stage, SAG and ball mill grinding circuit has been proposed to reduce the crushed material to a P80 of 38 µm for feed to flotation. The ball mill will operate in closed circuit with a cluster of 250 mm diameter cyclones. The cyclone overflow will report to a horizontal, vibrating trash screen 2.4 m wide by 4.8 m long
