In situ recovery, an alternative to conventional methods

Copper is the most popular commodity (after uranium) that is mined by ISR (Table 1). There are references to primitive forms of in situ leaching of copper in Roman times, and maybe even long before that in China (O'Gorman et al., 2004). The San Manuel copper mine in Arizona is the best known copper mine exploited by ISR (O'Gorman et al., 2004).
