The discovery of new resources is challenging both in well-understood geological environments and new settings (Section 3). Successful discovery does not, however, guarantee economic and socially acceptable exploitation. In this section, we review the range of mining and metallurgical processes required for economic extraction of mineral resources, along with the environmental and social constraints influencing development. Examples of major mines of different types and mining processes, discussed in this section, are shown in Figures 4.1 and 4.2.

Pictures of mines and mining equipment. (a) Bingham Canyon open pit mine exploiting a porphyry Cu-Mo-Au deposit. (b) Morenci open pit mine exploiting a supergene and hypogene porphyry Cu deposit. (c) Kiruna Fe mine – historical open pits now replaced by bulk underground mining. (d) Hemlo underground Au mine. (e) Typical large shovel operating in an open pit. (f) Large haul trucks (200–300 tonnes capacity) typical of major open pit mines.
