The results obtained show that weight retained varies from 36.71 g to 183.1 g for granite while that of iron-ore vary from 9.65 g to 87.78 g. In addition, it was observed that granite and iron-ore have grindability values of 0.061 g/rev and 0.926 g/rev respectively. This confirmed that granite requires more energy to be grinded.
