Leaching solution is pumped into the deposit where it comes in contact with the ore. The solution bearing the dissolved ore content is then pumped to the surface and processed. This process allows the extraction of metals and salts from an ore body without the need for conventional mining involving drill-and-blast, open-cut or underground mining.
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 pit floor, underground mine or floating vessel through pre ...
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 ]

Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation or restoration of the land after the mine is closed.

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.
Many different techniques in leaching were quickly employed at a large scale. [4] Both synthetic resins and organic solvents were used early on to extract uranium . [ 4 ] Ultimately, the use of organic solvents was less tedious compared to ion exchange through synthetic resins, and further production of uranium and other rare earth metals moved ...
