delivered ore and have in place measures to control this variability. Normally ore is hauled by haul trucks from the blasted mine face to an ore pad in front of a crusher, where it is dumped into some form of pre-crusher stockpile. When required for crushing, the stockpiled ore is picked up by a front-end loader and dumped into the crusher.

Automating material tracking through the coarse ore …

The idea behind a coarse ore stockpile (COS) is to reduce material hardness and grade variations in the mill. There is enough material change to detect from the incoming and outgoing material given the relatively small size of most COSs. If we achieve a perfect, uniform blend, the problem would be solved.
