In situ leaching (ISL), solution mining, or in situ recovery (ISR) involves dissolving uranium in the ground and pumping the solution to the surface where the minerals can be recovered. Information from the World Nuclear Association, the global private-sector organization that provides information on nuclear power, nuclear energy, and the role of nuclear in sustainable development.
The solvent extraction process, as applied to uranium treatment, is a liquid-liquid method of ion exchange in which the uranium content of the acidic aqueous solution is selectively transferred to an immiscible organic chemical solvent. The uranium depleted aqueous solution is termed raffinate and is phase separated
This process produced more dense and morc rapidly filtered precipitates than those formed by the addition of aqueous amonia or slurried calcium hydroxide. Thc filtrates from the anhydrous ammonia process were lower in uranium content than those obtained by the addition of the other reagents.

Uranium ore is simply rock with elevated amounts of uranium in it. Once the rock has been removed by open pit or underground mining it must be milled to separate the uranium from other constituents. The milling process for uranium is similar to that used for other metals such as copper, gold or nickel.
McClean Lake site is comprised of several uranium mines and one of the most technologically advanced uranium mills in the world—the only mill designed to process high-grade uranium ore without dilution. AREVA has operated several open-pit uranium mines at the McClean Lake site, and is evaluating future mines at and near the site. McClean Lake

Considering the actual period of time the hazards from uranium mining and milling wastes persist, these regulations are of course only a compromise, but they are a first step, at least. Regulations for the protection of groundwater were not included in the initial legislation; they .
Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining. The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged.
