Comminution is the most energy intensive component of mining and mineral processing and is extremely costly. Relatively simple process flowsheet strategies such as gangue rejection/ preconcentration, selection of coarser grind sizes and the application of newer crushing and grinding technologies will assist in minimising costs and carbon footprint. Yet, despite systematic and detailed research in this area, the industry remains somewhat reluctant to implement these strategies.
