Also, the fluctuations on the flow rates (e.g., circulating load, fresh feed) and the power draws (e.g. classifier, mill and elevators) were all monitored from on the control room. Data recorded from control room when the steady-state conditions were established is tabulated in Table 4 .
It is imperative to ensure the efficient removal of both slurry and coarse pebbles (critical size) in order to ensure the efficient operation of AG/SAG mills. Elimination of the above mentioned material transport problems will allow the mill to respond truly in terms of power draw for changes in mill load which depends on feed ore characteristics.
