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.
Figure 4.1

As discussed in Sections 1 and 3, the economically extractable portion of a demonstrated (i.e. measured and indicated)...
