For instance, if the processing cost was R200 per ton, a dilution rate of 88% would mean that R176 is spent on processing waste as ore in the mill. It is clear that the mill processing costs would increase directly by an amount equal to the dilution factor. Reduction of external waste would result in less tonnage at a higher grade being sent to ...
