Estimating the Optimal Overall Slope Angle of Open-Pit Mines

As a result, the total costs of overburden removal and ore recovery are $ 23.5 × 10 6 and $ 320 × 10 6, respectively. It is important to note that the total operating cost includes both the cost of ore extraction (e.g., $ 320 × 10 6) and the cost of overburden removal (e.g., $ 23.5 × 10 6). As a result, the total operating cost is 343.5 × ...
