This block will be considered as waste after 10% dilution. Table 1 – Effect of Dilution on Ore Grade in a Gold Mine Original Ore (g/t) Dilution (%) Waste Au (g/t) Mill Feed (g/t)

WebDilution is common to all mining operations and it’s impossible to eliminate. (Butcher, 2000), defines mine dilution as the contamination of ore with barren (or below cutoff grade) waste wall rock. Dilution is a qualitative parameter used by the mine operator for evaluation of the design (Pakalnis, 1986).
