Research Highlights Wet grindability of a diasporic ore was investigated in a laboratory ball mill. Three size-intervals fitted first-order breakage, but the coarsest interval did not. The non-first order was most probably caused by the heterogeneity of the material. Breakage parameters were back-calculated and validation results are in good accuracy. …
