Integrated comminution and flotation neurocontrol using …

The comminution and flotation circuits both contribute to maximizing the venture profit associated with the concentratel. The comminution circuit conditions the ore for optimal liberation and surface chemistry for improved recovery and grade in the flotation circuit. Since the comminution circuit''s liberation is not measurable on-line, the control objective for comminution attempts to maintain a particle size distribution deemed optimal for flotation. Disturbances to the comminution circuit, such as ore hardness and feed particle size variations, lead to suboptimal particle size distributions, affecting the flotation unit adversely. In addition, flotation circuits are perturbed by numerous disturbances unrelated to comminution, viz. mineralogical composition, varying solution composition and ore surface changes. Other than supplying a fixed particle size distribution, current grinding circuit control schemes do not take the current operating condition of the flotation circuit into account. Comminution circuit control actions are based purely on sensor information from the comminution circuit. Similarly, typical flotation control strategies do not consider how the current operating condition of the grinding circuit impacts the flotation …
