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 The Beverley uranium mine in Australia uses in situ leaching.
In situ leaching of copper can only be used as an extraction All three mines are located in Arizona and include: Excelsior deposit, oxidizing and dissolving the in situ uranium mineral.
