Mining is also expensive and known to cause many environmental issues related mainly to toxic mine wastes and habitat destruction. In-situ leaching (ISL) methods, however, are increasingly allowing certain deposits to be mined without excavation, sidestepping some of the most destructive, and costliest, parts of mining. What is ISL?
