in situ leach mining
Situ Leaching - an overview | ScienceDirect Topics
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.
