uranium ore is a mixture of valuable - Le Palais du Dragon

Unfortunately, U235 is relatively rare (approx. 0.71% of natural Uranium ore) so the uranium ore is processed to provide a mixture that has more of the U235 isotope in it (around 4%). This is called "enriched uranium." The byproduct of this processing is U238 with almost no U235 in it at all, and that is "depleted uranium."

ATSDR - Toxic Substances - Uranium

Mar 03, 2011· Uranium is a common naturally occurring and radioactive substance. It is a normal part of rocks, soil, air, and water, and it occurs in nature in the form of minerals - but never as a metal. Uranium metal is silver-colored with a gray surface and is nearly as strong as steel. Natural uranium is a mixture of three types or isotopes called U-234 (234U), U-235 (235U)and U ...

Uranium - Wikipedia

Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table.A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years.
