Since 1970, all commercial-scale ISL mines in the US have used carbonate solutions. [4] [5] ISL mining in Australia uses acid solutions. [6] Ion exchange resin beads. In-situ recovery involves the extraction of uranium-bearing water (grading as low as 0.05%, or 500 ppm, U 3 O 8). The extracted uranium solution is then filtered through resin ...
Solvent extraction and electrowinning (SX/EW) is a two-stage hydrometallurgical process that first extracts and upgrades copper ions from low-grade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent.
Brine mining is the extraction of useful materials (chemical elements or compounds) which are naturally dissolved in brine. The brine may be seawater , other surface water , groundwater , or hyper-saline solutions from several industries (e.g., textile industries). [ 1 ]
Borehole mining tool and technology principle schematic. Borehole Mining (BHM) is a remote operated method of extraction (mining) of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jetting (hydraulicking). This process is carried-out from a land surface, open ...

Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas in situ mining lacks these liners and pulls pregnant solution up to obtain the minerals. Heap leaching is widely used in modern large-scale mining operations as it produces the desired concentrates ...
Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. [ 1 ] [ 2 ] Processing techniques that complement hydrometallurgy are pyrometallurgy , vapour metallurgy, and molten salt electrometallurgy.
