recovery of uranium from iron ore

Uranium Recovery NRC.gov

What We Regulate As the precursor to the nuclear fuel cycle, uranium recovery focuses on extracting (or mining) natural uranium ore from the Earth and concentrating (or milling) that ore. These recovery operations produce a product, called " yellowcake," which is then transported to a fuel cycle facility.

Uranium Recovery (Extraction) Methods NRC.gov

In the in-situ recovery (ISR) process, a solution called lixiviant (typically containing water mixed with oxygen and/or hydrogen peroxide, as well as sodium carbonate or carbon dioxide), is pumped into the subsurface. The lixiviant dissolves the uranium into the solution.

Heap leaching Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. 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
