dc.description.abstractThe development of realistic comminution models is dependent on the accuracy with which ore breakage can be predicted. This hinges on our understanding of the basic concepts of breakage and the different modes in which it manifests in the comminution environment. Three distinctly different modes of breakage were identified and investigated as the elementary processes that govern comminution. Impact breakage was investigated as the first mode of breakage. Drop weight tests were performed to determine the influence of different energy intensities on the product particle size distribution. The drop weight tests were carried out on UG2 platinum and Target gold ore. The particles were broken over a range of six size classes ranging from 13 to l06mm. It was observed that the product size distribution becomes finer with increasing energies and that the sub 400um fraction may contain valuable information for some ore types.en_ZA
