    THE IMPORTANCE OF DILUTION FACTOR FOR OPEN PIT .
    Table 1 shows the effect of 10% dilution on ore grade for a gold mine for one tonne of ore. Assaying showed that waste rocks have a small amount of gold. The gold grade in waste rocks is gram per tonnes. The milling cutoff grade for this operation is calculated to be /t. It means that a tonne of ore with /t can be sent to the mill and be expected to generate a small amount of ...
