Özet:    Breakage characteristics of magnetite, platinum and phosphorite ores were investigated via compressed bed breakage tests. With this aim, piston-die test equipment was used. Effects of specific comminution energy (ECS) and particle size on breakage was investigated by using obtained data from the breakage tests. The relationship between ECS (Specific Comminution Energy) and t10 value, which is commonly used in literature, was established. Then, the product fineness and particle size relationship were analysed, and the compatibility of the data obtained from the tests, with size dependent breakage model was evaluated. It was concluded that the size-dependent breakage model better fitted to the data than the size-independent model and this model could be used to determine the breakage behaviour under compression force.
