Cutoff grade estimation
CutOff grade is the minimum grade required in order for a mineral or metal to be economically mined (or processed). Material found to be above this grade is considered to be ore, while material below this grade is considered to be waste. Although in a variety of units can be used, the cutoff grade is usually expressed as:
Polymetallic deposit cutoff grade estimation ...
The mill cutoff value is the difference between the mine operating cost and the mining cost. Appliion of NSR Models NSR models can be used to economically evaluate a polymetallic deposit at the exploration stage, evaluation stage, as well as the exploitation stage.
