Easy profit maximization method for open-pit mining - ScienceDirect

Thus it allows estimations of exploitable reserves in function of various cut-off grades, such as the average grade of mineable ore, the tonnages of ore and waste rock, stripping ratios and profit estimates for different production levels. If cost evaluations of essential mine operations are available (such as ore mining, waste.

Open pit mining profit maximization considering selling stage and .

In open pit mining activities, determination of the cut-off grade becomes crucial for the company since the cut-off grade affects how much profit will be earned for the mining company. In this study, we developed a cut-off grade determination mode for the open pit mining industry considering the cost of mining, waste removal.
