Includes bibliographical references. === The significance of this study is primarily intended to provide better understanding of axial segregation and flow of particles along SAG mills. Additionally, the current SAG mill models developed using "short" Australian and North American style mills exposes inaccuracies when applied to predict the performance of "long" mills. Thus the results of this study are expected to be useful for improving modelling of long SAG mills. Several studies of radial and axial segregation in tumbling horizontal devices at laboratory-scale and a few on pilot-scale have been conducted in the past by various researchers. Recently, industrial-scale studies of axial segregation in kilns and dry milling, particularly in the cement industry have also been conducted. However, there seems to be no work reported and cited in the literature on axial segregation studies along SAG mills. Thus the lack of previous segregation research along SAG mills has exposed a knowledge gap in the subject.
