Abstract - USGS

Operating costs are based on daily capacity (st/d) and are expressed in dollars per short ton ($/st). The open pit models are based on X = st/d of ore and waste moved. This allows for the wide variability in stripping ratios found among different open pit operations.

Open-Pit Mining Methods

2 天前 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 ...

Scale, 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.

2012-12-11 Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002).
