What is Uranium? | IAEA
There are three natural isotopes of uranium — uranium-234 (U-234), uranium-235 (U-235) and uranium-238 (U-238). U-238 is the most common one, accounting for around 99 per cent of natural uranium found on earth. Most nuclear reactors use fuels containing U-235, however, natural uranium typically contains only 0.72 per cent of U-235 and, most reactors …

Uranium Mining
Natural uranium refers to uranium with the same isotopic ratio found in nature. It consists primarily of isotope 238 U (99.28%). Therefore the atomic mass of the uranium element is close to the atomic mass of the 238 U isotope (238.03u). Natural uranium also consists of two other isotopes: 235 U (0.71%) and 234 U (0.0054%). The abundance of ...

Uranium Ore (Carnotite). 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.

Mining and concentrating. Uranium ores occur in deposits that are both near-surface and very deep (e.g., 300 to 1,200 metres, or 1,000 to 4,000 feet). The deep ores sometimes occur in seams as thick as 30 metres. As is the case with ores of other metals, surface uranium ores are readily mined with large earth-moving equipment, while deep deposits are …

Uranium Extraction Process
Uranium Ore is hauled by truck to the mill site, where it is weighed and a grab sample taken for moisture. Truck loads from each respective ore supplier are then dumped on a stock lot until 150-200 tons are accumulated at which time it is delivered to a 50-ton receiving hopper for passage through the crushing and sampling plant.

Uranium Mining and Milling
Tailings: Milling uranium ore produces tailings. Tailings are what is left over once the uranium has been removed from the ground rock and resemble fine sand. They contain long-lived radionuclides (such as thorium-230 and radium-226) produced from the decay of uranium, as well as trace metals like arsenic and nickel.
