Nevertheless, the model of  can be further extended to estimate costs of other types of open. pit mines. Khousavand et al  developed models, which included costs uncertainty in. stockpile of open.
Operating costs are the physical costs of pro- ducing copper: the direct and indirect costs in- curred in mining, concentrating, smelting, and refining copper. They include transportation to the mill, smelter, and refinery, and metallurgical processing of the byproducts. Some estimates of operating costs also include the freight.
They argue that mineral production in Australia has become unsustainable because of the high external costs. In the USA, the grade of mined copper has declined from more than 2% in the early part of the 20th century to 0.5% at the beginning of the 21st century (Tilton, 2003). During the same period and also in the USA,.
In 2013 global copper mine production was estimated to be about 18.3 Mt, with Chile being the largest producer, followed by China, Peru and the USA (U.S. Geological Survey (USGS), 2015), while global smelter production of copper reached 13.8 Mt if only primary production is considered (Minerals U.K., 2015) or 16.8 Mt.

These models then inform the mine planning strategy that optimizes cash flow and NPV, and also allow the development of a stockpiling strategy that not only stabilizes the plant, but also allows variations in the plant feed according to ore type and grade in volatile price scenarios. Integral to the realization of these.
Mar 14, 2016 . For 86 years, the Magma Superior mine pulled copper and silver out of the surrounding mountains before closing in 1996 when the minerals ran out. . The Resolution mine is essentially an enormous bet that the third-most-used metal in the world is oversold and that prices will rebound by the time the mine.
