Following the acquisition of grinding-circuit data at Brenda Mines Limited for simulation purposes, various methods to mass balance the circuit were evaluated. Unfortunately, different answers were obtained for different balancing methods. A data-adjustment procedure was therefore developed.
Free QuoteThe mass balance indicated that the circuits were similar, with the same throughput and same P 80, but as discussed in the online data analysis, the significant difference between the circuits was the production of slimes, and the desliming circuit wasn’t sampled. However, the size distribution analysis completed within the grinding circuit ...

Currently, the grinding circuits are inefficient in achieving the aspired product fineness of xP,80 = 125 μm even at low to normal throughputs (450-600 t/h). An evaluation and optimization study of the circuit performance was conducted to improve the product fineness through circuit surveys, experimental lab work and simulations.
