Operating Costs, AISC | Mining Data Online

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 stripping. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit ...

Surface mining planning and design of open pit mining

Typical open cut grades. Gold is generally extracted in open-pit mines at 1 to 5 ppm (parts per million) but in certain cases, 0.75 ppm gold is economical. This was achieved by bulk heap leaching at the Peak Hill mine in western New South Wales, near Dubbo, Australia.. Nickel, generally as laterite, is extracted via open-pit down to 0.2%. Copper can be extracted at …

Operating Cost for Miners | SRK Consulting

Jan 01, 2017· Daily expenses such as chemical and electricity costs are listed as operational expenses. The authors found that maintenance costs varied for each mine site and ranged between 0.2% and 1.45% of total capital costs. Therefore, this analysis used the median value of 0.83% of total capital costs when estimating the maintenance cost.

Final Report October 2001 Report by Symonds Group, in

At peak production, Oyu Tolgoi is expected to operate in the first quartile of the copper cash cost curve and by 2030 is expected to be the fourth largest copper mine in the world. It is expected to produce 480,000 t of copper per year on average, from 2028 to 2036, from the open pit …

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 ...

A New Cost Model for Estimation of Open Pit Copper Mine ...

Mine closure is expensive Large open cut mines can cost hundreds of millions - and some cases - over a billion dollars to close. Currently, the Ranger Uranium Mine and Century Mine (zinc) are the two largest mine closures to date. These two mines will cost in the vicinity of $750m to $1bn to close once complete,

Open Pit Mine Design, Planning, and Engineering ... Mine cost estimation may be done at many levels. At first it may be a simple "back of the envelope" estimation using similar operations to benchmark against. Later it may be decided to use an existing mine that the company owns and factor and compare costs against them.

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.

A Simplified Economic Filter for Open

OPEN PIT MINE MODELS. Two open pit models were developed, a small tonnage and a large tonnage model. The small tonnage model is valid for operations with daily capacities of 500 to 20,000 st/d of material moved (ore and waste). For the large tonnage model, applicable capacities are 20,000 to 200,000 st/d.

Nov 20, 2017· For instance, in the case of an open-pit operation, the costs vary with the size of the ultimate pit, its average strip ratio, the mine life and also the greatness of the surrounding mine's facilities (Rahmanpour and Osanloo, 2017). Therefore, the reclamation cost estimator must take into account the pit, waste dump, tailing dam and other mine ...

The open-pit mine produced 443,000t of copper in 2011. Feasibility study is underway to switch to underground production at Chuquicamata by the end of 2018. The ore reserve under the existing pit is estimated to be 1.7 billion tonnes grading at 0.7% copper. The underground development project is estimated to cost more than $4bn.
