Uranium 238, the most prevalent isotope in uranium ore, has a half life of about 4.5 billion years; that is, half the atoms in any sample will decay in that amount of time. Uranium 238 decays by alpha emission into thorium 234, which itself decays by beta emission to protactinium 234, which decays by beta emission to uranium 234, and so on.

Uranium processing Uranium processing Leaching Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. Acid leaching is commonly performed by agitating an ore

Uranium 235 can also be produced using the kovarex enrichment process. Uranium 235 is, along with uranium 238, one of the refined products of uranium ore. Both isotopes of uranium are the main ingredients for most components of nuclear power generation. Uranium 235 is much rarer than its counterpart, uranium 238.
