size distributions to that of abrasion. But, the abrasion experiments were conducted in a tumbling mill. Hence, the possibility of substituting low energy impact breakage for shear abrasion breakage was investigated as well. Abrasion tests and impact tests were conducted over a range of energies with the same ore type and the results were compared.
