In situ leaching of copper Challenges and future

Although most previous copper ISL projects have focused upon leaching copper oxide minerals, there have been some attempts to leach copper sulfide minerals in situ (Browne and Miller, 2002, Cathles et al., 1978, Doyle et al., 1997, Schmidt and Earley, 1997). Secondary copper sulfides (e.g., chalcocite) require oxidation in order to dissolve, generally provided by ferric iron.
