2010) In this study simplified engineering cost models were used to estimate the economic fraction of resources contained in undiscovered porphyry copper deposits predicted in a global assessment of copper resources The cost models of Camm (1991) were updated with a cost index to reflect increases in mining and milling costs since 1989
mining industry Australia has some of the world's largest coal reserves but is struggling with maintaining mining profit margins Slide 2 PwC Asia School of Mines 2012 November 2012 PwC Productivity and cost management in the mining industry
In this paper in order to achieve a reliable cost model the technical and economic data of 15 open pit porphyry copper mines have been collected The proposed cost model is developed based on
In this paper data of 52 open pit porphyry copper mines have been collected 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 Vector Regression (SVR) model is obviously better than Kernel Ridge Regression (KRR) model to predict the mining CAPEX

22/05/2019Scale grades processing costs open pit vs underground The interesting aspect of the AISC metric is the number of factors that feed into the final figure and similar to any other sector costs they can vary from month to month and year to year In the case of gold stocks better grades usually translate into lower cost mines in case of openpit mines with large size fleet the biggest cost items are diesel tyres and spares In case of manual underground mines the biggest cost items would be wages What is China's mining?Get price
Cost estimation in mining According to Hall (2013) there is a lack of general estimates of capital costs for establishing coal mines in South Africa In a 2008 regression analysis study the Australian Average Capital Costs (ACC) for developing an open-pit mine were estimated as Pamour is a Gold-Copper Mine (Ontario) in Canada owned by Goldcorp General In the second half of 2009 mining of the Pamour Open Pit ceased and hauling of stockpiled medium grade material from the Pamour site to the Dome mill For more data on production status ownership capex and other categories see the data sectionGet price
open-pit design and mine planning by R M Jara* A Couble* X Emery† E J Magri† and J M Ortiz† Synopsis This work evaluates and characterizes the impact of the support size and mining dilution of a block model in the operation and selection of equipment at an open pit mine An exploratory analysis and01/01/2007The estimation of dilution and ore loss is therefore an essential part of any Ore Reserve estimate or mine schedule Large open pit mines are driven by the economies of scale that are achieved at the cost of less selectivity in the discrimination of ore and wasteGet price
Long and Singer further studied Taylor's rule in 2001 and calibrated it to 45 open pit copper mines The open pit copper model proved to have a curve halfway between the 1998 gold-silver curve and Taylor's Rule This is due to base metal mines having less aggressive production rates than precious metal mines Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface If the deposit apexes below the surface the overburden and barren capping overlying the ore must be removed in advance of open-pit mining The removal of this material is known as strippingGet price
Ask an Expert Jennifer Leinart A licensed professional geologist and cost estimator leading the CostMine division With over 35 years of mining industry experience from exploration through development and operations she now specializes in project evaluation economic analysis cost estimating and consulting services In general underground mining is more expensive than open pit mining as with open pit mining the minerals are found near the surface at a maximum of approximately 200-400 meters depth in bulk tonnage The mining costs are estimated in a mining company's feasibility study which when available can be found on the company's website (often hidden between the news releases)Get price
The outcome of this estimate is what I refer to as the adjusted mineral deposit value You also can not expect that this adjusted mineral deposit value is the price the mining company will receive from a buyer when this property is sold as for instance the costs of extracting the metal from the ore and other operating expenses are not deducted from the mineral deposit value A prefeasibility study (PFS) for the King of the Hills gold project in Western Australia has estimated a capital cost of A$218-million to develop an openpit mine supporting a long-term bulkGet price
