Purpose of this project was to investigate the effect of grinding conditions, e.g., pH, P/sub O/sub 2//, grinding media composition and, in particular, size of mill on the wear rates and wear mechanism for both a molybdenite ore and a magnetic iron ore. This allowed data to be obtained on the correlation of scale-up between small diameter laboratory mills and industrial mills and provided a relatively inexpensive test method to be developed for the selection of grinding media used with different ores. Secondly, the effect of the physico-chemical properties of the slurry on wear mechanism(s) and wear rates was evaluated using various slurry media and additives. Results of this work were aimed at providing information from which a more efficient selection of grinding media and conditions may be made which will reduce the total energy consumed in the grinding of minerals.
