APPENDIX 2: CAPITAL AND OPERATING COST ESTIMATE GR
The final design had a capital cost of approximately $200M The scope of this current estimate was restricted to the Kundip resource and considered just two metallurgical domains the low copper oxide and the high copper sulphide This greatly simplifies The purpose of this paper is to establish formulae that can be used for estimating capital costs of developing coal mines in a coal (PDF) A New Cost Model for Estimation of Open Pit
Mining capital cost estimation using Support Vector
This study tries to benefit from Support Vector Regression theory to develop a cost estimation model The research indicates that the performance of the Support Applied across the industry, improved coarse particle flotation can result in an additional 05 million to 15 million metric tons of Copperprocessing technologies: Growing global
Capital and operating costs of minerals engineering
For example the capital cost for an underground copper mine with associated concentrator will be much higher than a simple heap leach operation for The model shows that the processing cost would be 2,953 US$/t of Cu, for a plant that processes mine tailings to obtain copper through hydrometallurgical Estimating processing cost for the recovery of valuable elements
Estimating the Capital Costs of Electrowinning Processes
The new model for capital cost describes within ±30 to 100% the capex for existing electrochemical processes, sufficient for order of magnitude and preliminary In this paper, to estimate the capital cost of mining projects, a model based on Support Vector Regression (SVR) is developed To establish this model the technical Mining capital cost estimation using Support Vector
Estimating the Capital Costs of Electrowinning Processes

Alternative Models for the Calculation of CAPEX and OPEX for a
process equipment, for example a leach tank, based on process data in combination with the calculation of mechanical properties Furthermore, it calculates the CAPEX based on construction material cost and adequate machining surcharges Thus, a single cost model for a leach tank is adequate for both copper and other hydrometallurgical plants andprocessing costs Therefore, the mine stated “there is no universal standard in estimating costs for surface costs in open pit mines are categorized into four groups: (1) capital costs, (2)Cost estimation for open pit mines: Tackling cost uncertainties

Potential cost savings measures This study has found that in general the relative Mining and Milling costs of a given operation do not significantly differ, and generally fall within the range of 43:43:14 to 45:45:10 (Mine:Mill:G & A) In addition, G & A costs were found to be consistently lower than both Milling and Mining costsInstead, we propose a capital cost model for electrochemical processes based on relevant operating parameters such as current density, temperature, and voltage The new model for capital cost describes within ±30 to 100% the capex for existing electrochemical processes, sufficient for order of magnitude and preliminary design Estimating the Capital Costs of Electrowinning Processes
