Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is ...

MINING OVERVIEW Introduction The U.S total domestic mining and waste removal for nonfuel mineral materials production amounted to 5.9 billion metric tons (Gt) in 2007 (most current year final statistics are available). These materials included 4.5 Gt of crude ore mined or quarried and 1.4 Gt of mine ore and waste from development operations.

The mining process is used to separate rock or ore from surrounding rock. There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. The method used depends on the type of mineral resource that is mined, its location beneath the surface, and whether the resource is worth enough money to justify extracting it.

2 Economic differences in the nature of mineral deposits is evident in the. following terms: Ore: a mineral deposit that has sufficient utility and value to be mined at a profit. Gangue: the valueless mineral particles within an ore deposit that must be discarded. Waste: the material associated with an ore deposit that must be mined to get at the ore and must then be discarded.
