In-situ recovery—a move towards 'keyhole mining' - Mining3

In-situ recovery (ISR, also referred to as in-situ leaching or solution mining) may offer such a step-change approach. ISR refers to the recovery of valuable metals from ore deposits by the circulation of a fluid underground and the recovery of the valuable metal from the fluid at the surface for further processing.

Recovery of Copper by Solution Mining Methods

Recovery of Copper by Solution Mining Methods 3 Supplementing production from conventional heap leach operation, the in-place rubble leaching project at Silver Bell is estimated to recover 20 to 25% of the contained copper. The relatively low recovery achieved by this method is most likely due to the presence of insoluble hypogene
