摘      要：Particle size distributions of obtained samples from several sampling campaigns were determined and raw data were mass balanced before being used in simulation *** determination of breakage function,selection function,Bond work index,residence time distribution parameters,and Whiten s model parameters for air separators and diaphragms between the two compartments of tube ball mills,performance of the circuits was simulated for given throughputs and feed particle size *** s model parameters were determined by GA(genetic algorithm) toolbox of MATLAB *** on implemented models for modeling and simulation,optimization of circuits was carried *** increased nearly 10.5% and 15.8% in fresh feed capacity input to each tube ball *** addition,circulating load ratios of circuits are modified to 118% and 127% from low level of 57% and 22%,respectively,and also cut points of air separators are adjusted at 30 and 40 μm from high range of 53 and 97 μm,*** applications helped in well-operation and energy consumption reduction of equipments.
