  • Costmine Industry Standard for Mining Cost Estimating

    Mining Cost Service continues to be a useful reference on a wide range of topics for early stage mine planning through to ‘fill the gaps’ on more detailed studies. Mining Cost Service provides an independent source for information on equipment, quantities and cost for a significant number of mining methods and range of production rates.

    Operating Cost for Miners SRK Consulting

    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. In the final stages a detailed bottom-up estimation based on first principles may be completed.

    Operating costs: Per ton basis (e.g., $2.50/ton for mining) Capital costs Cost of Capital Cost of capital is the minimum rate of return that a business must earn before generating value. Before a business can turn a profit, it must at least generate sufficient income to cover the cost of funding its operation. : Includes initial capital (construction of mine) and sustaining capital (ongoing

    Cost of Stoping for Underground Mining

    Stoping cost is one of the largest of the items comprising the total cost of producing ore. The cost per ton of ore mined is important but may be overemphasized if the more important cost, that per unit of metal recovered, is thereby overlooked. A given stoping method may give a low cost per ton of ore but, by reason of high dilution involving the handling, hauling, hoisting, and treating of a

    Double Unit Supersections as a Means of Reducing Cost

    01.01.1987· Where cost per ton must be reduced, and the level of production must be maintained, combining two regular continuous mining sections into a double unit supersection is a viable method of reducing cost per ton. The resulting simplification of the mining system which is attained by consolidating two continuous miner sections into a double unit supersection can lead to a lower cost per ton

    Here’s an example. Let’s consider a mining operation where 10 million cubic meters (in-situ) per year of material needs to be transported 3 km; thus a 6-km, 20-minute, return trip for trucks. This stone might be achieved using two 350-ton excavators and a fleet of twelve 140-ton trucks, operating 5,800 hours per year. To support this fleet

    Australia’s gold mines by production, grades and costs

    As a case in point, a mine that produces 100,000 ounces of gold and 10,000 tonnes of copper per year at a cost of US$1000 per ounce, not including revenues generated from the sale of copper, will have AISCs well below US$1000 per ounce after the by-product credits are taken into account.

    Open-Pit Mining Methods

    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

    The recent increase in ammonium nitrate and diesel oil prices have invited many operations in mine to re-examine their drilling and blasting methods to find ways of reducing costs. Under the changed scenario, drilling and blasting companies require to optimize their blasting and costs through a blasting optimization review. Some of the questions faced during blast optimization are discussed here.

    01.01.1987· Supply Cost The conversion to double unit supersections resulted in a decrease of the supply cost from $9.00 to $6.00 per ton of clean coal mined. This reduction came from materials which could be utilized between the two sections comprising the double section such as beltline structure, brattice blocks, and rock dust.
