1 introduction. traditional rock comminution practices (crushing and grinding) suffer from considerable drawbacks, such as high levels of energy consumption 1, 2 and high wear of the equipment. one approach to overcome these drawbacks is the development of a preconditioning treatment that weakens the mechanical properties of rocks before subjecting them to further.
A geometallurgical model requires accurate sampling of ore variables (deutch, 2013). rock strength is one such variable. usually, rock strength modelling is based on a calculated average for the rock type which disregards textural differences (hayes and piper, 2003). textual changes were incorporated into the data-set to represent more accurate.
