In nature, U-235 only makes up a very small part of the uranium ore. Given its importance for nuclear power and nuclear weapons technology, U-235 is often removed from the natural uranium ore and concentrated through a process called uranium enrichment. DU is the material left behind after enrichment. Like the natural uranium ore, DU is ...

US Uranium Mining and Exploration - World Nuclear Association

When present in compounds, uranium exists mostly in oxidation state IV and oxidation state VI. All isotopes of uranium are radioactive, some more so than others. Its radioactivity – in particular its capacity to undergo thermonuclear chain reactions – has led to uranium’s use in energy generation, both for civilian and military purposes.

Many contemporary uses of uranium exploit its unique nuclear properties. Uranium-235 is the only naturally occurring fissile isotope, which makes it widely used in nuclear power plants and nuclear weapons. However, because of the tiny amounts found in nature, uranium needs to undergo enrichment so that enough uranium-235 is present.
