     distributed performance of a flotation bank, consisting of a number of cells in series is determined for different purposes such as process design, scale up, diagnosis, operation and control and optimization. traditionally in plant operation mass balances around the whole flotation bank is developed in order to characterize the overall recovery typically in rougher floatation. however, carrying out experiments to fit flotation rate models are seldom undertaken on industrial floatation banks due to laborious sampling, preparation and analysis. in this work, in order to investigate the effect of particle size distribution of rougher cells feed on metallurgical characteristics at sungun copper plant, kinetics of different size fractions through rougher bank was studied by using both traditional method and yianatos method which depends on collecting samples from only five points. it is indicated that, the yianatos method can be beneficial in kinetic rate constant determination for the whole size range and -75 μm fractions.
