concentrations over large areas, surface, or open-pit mining, is the predominant method of copper mining globally. After mining, copper is produced by one of two process routes: pyrometallurgical or hydrometallurgical. Within the pyrometallurgical route, the mined ore is crushed and milled, followed by a concentration step using flotation.

Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this. Mining then follows the vein of ore and the underground mine develops. In both mining techniques, the mined ore must be removed from the mine and transported to a plant for processing and refining. Trucks and trains are used for this purpose.
