Situ Leaching - an overview | ScienceDirect Topics

Ian Hore-Lacy, in Encyclopedia of Energy, 2004. 1.3 In Situ Leach (ISL) Mining. In situ leaching (ISL), also known as solution mining, involves leaving the ore where it is in the ground and using liquids that are pumped through it to recover the minerals out of the ore by leaching. Consequently there is little surface disturbance and no tailings or waste rock generated.
