Open-pit mining provides significant proportions of many of the world's major mineral commodities. Much of the world's annual output of copper, gold and iron ore is won from open-pit operations. Other commodities produced from open-pits include diamonds, molybdenum, manganese, lead and zinc, uranium and a variety of industrial minerals, In open-pit mining a large proportion of the matter which is removed from the mine is processed and then discarded. Miners are searching for minerals such as copper, gold or iron ore for example. The rock and earth removed from the mine in the first instance is not the target for the miners, but the above mentioned minerals which exploration technics Surface Mining & Quarrying Techniques & Methods Epiroc
