The comminution circuit comprises two-stage crushing and single-stage grinding in a ball mill in closed-circuit with a high-frequency screen. A detailed circuit audit was undertaken at mm were replaced with 80 mm balls to reduce the amount of coarser particles in circulation. Larger balls reduced the number of particles coarser than 1 mm by about 5%. In case the feed to ball mill was equal to 1200 Mg/h, it resulted in a reduction of 60 Mg/h of the weight of coarse particles in circulation.
