(PDF) COST ESTIMATION FOR OPEN PIT MINES:
This article presents cost models for open pit mines, which takes into account cost uncertainty. In this paper, cost uncertainty is 2.1 Cost Categorization. In this paper, costs in open pit mines are categorized into four groups: (1) capital costs, (2) operating costs, (3) general and Cost estimation for open pit mines: Tackling cost

Determining the environmental costs of mining projects
Applying the methodology to the Songun copper mine dataset revealed that the environmental cost per ton of extracted materials was $0.02927 and $0.02145 for open-pit and block-caving sections, respectively. The difference in costs is due to the higher environmental impact of open-pit activities, requiring higher costs to prevent, reduce, andFor the reason, ascendant trend of operating cost per each tonnage of produced ore in regard to different open-pit mine sizes, is assessed using whittle 4-X software (Fig. 2). As it is clear inMining operating costs of open-pit and underground.

Green and climate-smart mining: A framework to analyze open-pit
However, the level of eco-environmental destruction in open-pit mining regions is ten times higher than in other mining areas (Zhou et al., 2018). According to statistics in 2018, China has 67,700 mines with an annual mining capacity of more than 30 billion tons, which destroy over 4 million hectares of land, and tailings waste rock The location of the deposit decides which type of mine can be set up. For example, an open pit mine cannot be started if the deposit is at a depth of 1,000 m. The quantity of ore extracted every year, the rate of extraction, differs between different types of mine. An open pit means that more ore can be extracted at a lower extraction cost.Geology and mining — MineFacts

Forecasting mining capital cost for open-pit mining projects
The advanced techniques in mining industry are also the influence methods on MCC as well as NPV of an open-pit mine (Demirel et al., 2018; Mai et al., 2018; Miao et al., 2017; Richmond, 2018; Rimélé et al., 2018; Ristovski et al., 2017). In briefly, MCC is a factor that has a great effect on the success of an open-pit mine project.So the cash costs per tonne of ore after credits are 0.6 × 0.75 × 22.046 × 0.9 × 0.45 US$/t = 4.02 US$/t Now we have to add the credits from the molybdenum contribution, which is per tonne: 0.01 × 22.046 × 0.8 × 2.50 US$/t = 0.44 US$/t To arrive at the operating cost per tonne OPC we have to add the credits from molyb-denum to that ofCalculation of Cost Data Springer

Optimal Selection and Assignment of Loading Equipment for
Open-pit mining is a resource-intensive process since the profitability of the business is strongly related to the magnitude of the tonnage extracted. Therefore, it is necessary to use large equipment to extract and transport material from the mine. Manual assignment of equipment selecting the lowest cost per ton. case B: Manual assignmentMining requires adits, drifts, shafts and narrow slopes. If a vein system occurs near the surface it may be possible to mine by open pit methods which would greatly reduce mining costs.
