Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Typical recoveries of 90% of the coal seam are achieved through open cut coal mining methods. However the environmental rehabilitation of sites is costly and must be achieved effectively according to regulatory requirements. Open-cut mining is also used for some iron ore, gold and copper production in Australian mines.

For iron ore mines, the stripping ratio ranges around 2-2.5.15 This means that for every tonne of iron ore produced, double the quantity of waste is generated. In 2003-04 itself, SAIL generated 4.76 million tonnes of overburden and rejects from its 12 mines in the country.16
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.
