The process of enriching uranium Uranium enrichement isolate a specific chemical elements isotopes Isotope separation of the component for the purpose of increasing the concentration of other isotopes to obtain the material is considered to be saturated with the isotopes, for example, to isolate certain isotopes of natural uranium for enriched uranium and depleted uranium. The enrichment process at stages where each stage is to isolate larger quantities of unwanted isotopes in growing element enrichment after each stage to reduce the proportion of the required purity.
For example, uranium is enriched uranium has been increasing the proportion of isotopes of uranium -235 and remove the other isotopes. The process of enrichment of these difficult and expensive and is difficult for the isotopes to be removed from the uranium very similar in terms of weight of the isotopes, which wants to keep the enrichment and the enrichment process is the use of heat through the liquid or gas to contribute to the process of removing unwanted isotopes are other more complex methods such as the use of laser or electromagnetic radiation.

Enrichment is the only component that can produce nuclear energy, contains natural uranium atoms are called isotopes Ktalat different and there are usually in the (uranium 238) and (uranium) 235. And ratios as follows:
• (uranium 238) - 99.3%
• (uranium 235) -0.7%
• other isotopes - 0,01

Stages of uranium extraction
1 - extract the metal from mining uranium ore (about 1-5 kg per tonne), then filtering and then transfer.
2- is a prelude to crush the metal extracted and the resulting powder that was built of yellow cake, which contains 70% of the uranium dioxide - (uranium oxide).
3- conversion of uranium oxide (yellowcake) into uranium gas Hecsa Floraid.
4- enrichment - in order to increase the content of uranium 235 isotope separation during the process - increase the proportion of U-235 separated from the uranium 238.
The enrichment process
1 - Enrichment is the process of separating uranium 238 and uranium 235, and by the gas centrifuge. Where the cylinder is fed Service (centrifuges) - which are administered on the basis of the engine - gas Hecsa Floraid uranium - uranium in his case goes to a gas centrifuge, and transferred from the 50-70 thousand rpm.
2 - gather the most weight molecules of uranium-238 on the wall of the cylinder and the land is less enriched uranium.
3 - the accumulation of particles lighter U-235 near the center of the cylinder and move up.
4 - U-235 is sent to a second uranium enrichment centrifuges, the gas feeding the next stage and then the slightly enriched uranium 235.
5 - Payment gas is depleted to slightly enriched feed 235 for the work due to the previous phase.

Enriched uranium
Enriched uranium is used in the manufacture of nuclear bombs, which should increase the level of U-235 before it is burned as fuel in nuclear reactors or the use of nuclear weapons.
Nuclear Weapons:
During the year 1500 the number of centrifuges to produce enough highly enriched uranium to produce one nuclear bomb. In the case of nuclear weapons, the level of U-235 above 90%, compared with uranium 238 and uranium 235 that is subject to combustion.
