The plant had a grinding circuit consisting of a primary ball mill (PBM) in an open circuit and a secondary ball mill (SBM) in a closed circuit with hydrocyclones with designing and operational characteristics presented in Table 1. The required industrial data were obtained through sampling at the designated points of the circuit, Fig. 1.
Additionally, lingering confusion about basics such as the relationship between circulating load ratio and ball mill circuit performance makes the optimisation objective seem nebulous to both plant metallurgist and designer.Some of this confusion can be eliminated by taking a step back from the overwhelming detail of sharpness of separation ...

The mill load and percent solids in the two streams are calculated from signals received by sensors in the water flow stream, the sump discharge flow rate and the density readings from density meters in the pulp streams. The mill load cells supply the charge mass. The load cell signals are compensated for pinion up thrusts [10].
purpose of designing and predicting the performance of grinding circuits. The CEET software tool is composed of . three primary components: • A process model for the SAG circuit (the SPI energy relationship). • A process model for the ball mill circuit (Bond's relationship-modified). • A data set of ore hardness.
Recovering these particles from the circulating load can not only boost overall plant recovery but can have an impact on mill capacity and also can lead to improved concentrate dewatering characteristics. Employing flash flotation in the circulating load has also been shown to stabilize the flotation feed grade to the main circuit.
the circulating load computed in this iteration. At the beginning of every the iteration, the feed of each unit operation must be computed because it depends on the circulating load and on the flow split. Figure 2 presents the proposed iterative algorithm for the closed circuit circulating load computation. It can be noted that the
