Reduce ore dilution and loss in open pit mines | BMT

Ore loss occurs when material containing grade (ore) is incorrectly sent to a waste dump. When a cost is given for Ore Loss, it is the sale value of the metal (gold, copper) recovered from this ore ( ore tonnes x grade x recovery rate x metal price). Dilution occurs when waste is unintentionally with material containing ore and sent to the ...
