geneous ores. Rod mill work index values often differ from ball mill work index values in the same type ore (40). In homogeneous ores the work index values tend to remain the same for different product sizes. As a supplement to this study, rod and ball mill grindability tests were run on the porphyry copper ore at sizes of 4 through 65 mesh
