Mine-To-Mill Optimisation: Effect Of Feed Size On Mill ,

For operations that have undertaken such an exercise in finer, improved fragmentation (for the mill’s benefit), the mine rarely is willing to return to the old ways of cost-minimised blasting The reason is that the mine also benefits greatly from more consistent fragmentation with less oversize material to deal with
