Chapter IX. General Discussion Of The Separation Of ...

Electromagnetic methods developed before 1941 had very high separation factors but very low yields and efficiencies. These were the reasons which - before the summer of 1941 - led the Uranium Committee to exclude such methods for large-scale separation of U-235. (See Paragraph 4:31.) Since that time it has been shown that the limitations are ...

Electromagnetic isotope separation method and its heritage

Uranium-235 had to be separated from natural uranium, where its content is as low as 0.72%. The production of plutonium-239 and the extraction of uranium-235 from natural ore were carried out in parallel, and one of technologies used to extract uranium-235, the so-called electromagnetic isotope separation, was developed by

High Gradient Magnetic Separation of Uranium Ores

Continuing interest in processes that will effect separations in the fine particle size range has prompted intense interest in the use of high gradient magnetic separation (HGMS) for beneficiation of uranium ores. Some of the uranium minerals are paramagnetic and hence are amenable to concentration by HGMS. HGMS is a powerful method in the upgrading of diamagnetic and paramagnetic minerals due ...

How is Uranium Enriched to Make Bombs? (with picture)

Electromagnetic isotope separation involves vaporizing uranium and then ionizing it to produce ions with positive charge. The ionized uranium was then accelerated at bent by a strong magnetic field. Lighter U-235 atoms were deflected slightly more, while U-238 atoms slightly less. By repeating this process many times, uranium could be enriched.
