In situ leach - Wikipedia
In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ.In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining.
Process to electrowin gold from acid mine water? - Finishing
There are ion exchange resins that are selective for gold and platinum group metals recovery from acidic waters. Typically, these are not regenerated. Instead, they are sent to a refiner where the resin is burned, followed by metal recovery from the ashes.
