Some Technical Aspects of Open Pit Mine Dewatering an aquifer affecting the stability of a slope in an open pit mine is a very efficient means of dewatering. The main advantage is a relatively low installation cost, no energy consumption for water discharge and low maintenance cost.

Long's 2009 study also found that introducing the variables grade and capital cost played a factor in estimating production rate, however expected tonnage was the primary factor. Long did generate equations involving grade and capital cost for open pit, however the inputs for these equations were not clarified. Applicability

Loading and hauling represent an important part of open pit mines production cycle and account for a considerable share of the total operating cost. The decision making during mine planning requires suitable and quick cost models. This paper intends to develop a model for estimating the capital and operating cost of major ...

Jul 10, 2018· As large open pit mines come to the end of their lives, many companies are examining the feasibility of transitioning to lowcost, largescale underground operations. Block cave mining is the only underground method that can offer comparable open pit production rates and operating costs.

Groundwork including backfilling of the Phase 2 pit has been completed, and full construction of the El Nino mine will begin in July 2018 with capital costs in 2018 estimated at million on a ...

Capital Costs: Total estimated capital costs of million (includes contingency) Sustaining Capital : Low estimated sustaining capital of million Mining : Open pit with g/t gold CutOff Grade, attractive strip ratio of and g/t Life of Mine gold grade

The above calculation method has amply clarified how cost calculations can be made. The mine planning for dumper transport inpit crusher with conveyor system are entirely different.

many years and require huge capital investment and risk. Each openpit mine is unique, based on the physical characteristics of the ore deposit and on the operational parameters of the extraction method; therefore, the most profitable way to exploit a mineral deposit requires ... capital cost is estimated at 286,645,232, annual fixed cost at ...

OpenPit Mining Methods. The economic limit for openpit mining is reached when the preparatory and stripping costs per ton of ore plus the openpit mining cost per ton of ore plus the cost of equipment, interest, and amortization charges equal the cost per ton by mining underground plus equipment and development cost and interest and amortization charges.

Capital Cost Used In Open Pit Optimization. EVALUATING CAPITAL INVESTMENT TIMING WITH . 227 journal of mining science, vol. 47, no. 2, 2011 evaluating capital investment timing with stochastic modeling of timedependent variables in open pit optimization.
