Fineness of the breakage products was represented by the t10 values and the relation between specific comminution energy level and t10 was established for the test materials. Typical relations between Ecs and t10 parameter are given for some of
the test materials in Figure 9. It was observed that, colemanite ore was broken easily compared to the other materials. Highest resistance to impact breakage was observed in the breakage event of quartz type II which belongs to a gold deposit
