Uranium

Mining uranium comes with a unique challenge: radiation. Uranium metal, concentrates, and by-products—especially radioactive radon gas—all pose a special set of risks and hazards. ... non-entry underground-mining methods. For lower-grade deposits that may rely on open-pit and underground mining methods, the search continues for more ...

Mining: Making the Most of Radioactive Caches

Underground mining calls for venturing deeper into underground mine systems, where miners use shafts or adits (vertical and horizontal tunnels) to move equipment and position workers throughout the mine. As we'll discuss later, mining underground for uranium poses higher health risks than other methods.

Uranium mining (open cut and underground) and milling

An example of an underground uranium mine using this method with backfilling is COMINAK's d'Akouta mine, Niger (Bibert, 1982, Areva, 2015). ... The use of remote-controlled mining equipment is likely to increase in the future, either to minimize the radiation exposure of workers or as an efficiency measure. This may allow mining in adverse ...

Uranium (U) Ore | Minerals, Formation, Occurrence, Deposits

The most common methods include open-pit mining, underground mining, and in-situ leach (ISL) mining. Open-pit mining: In this method, the uranium ore is extracted from an open pit or surface excavation using heavy machinery and equipment. This method is commonly used for uranium deposits close to the surface and with relatively high ore grades.
