Abstract In the comminution of heterogeneous bulk mixtures, the comminution behavior of the individual components plays a major role. The present study discusses the linkage between breakage of single ore components and their influence to the breakage characteristics of a defined bulk mixture. Thus, five components were identified from a heterogeneous gold ore material from Buzwagi Gold Mine in Tanzania by washing and manual sorting. The components were characterized in terms of particle size by sieving and composition by XRD. The breakage properties were determined by standard Bond test, batch grinding, and single particle tests. The breakage characteristics were linked to the composition of the components and the bulk sample. The study reveals differences in breakage behaviour of the components as well as their influence in the breakage characteristics of a heterogeneous bulk mixture.
