Annex 1 Process of uranium enrichment - WHO

Annex 1 Process of uranium enrichment After mineral extraction, processed uranium ore (or more exceptionally uranium generated from the recycling of nuclear fuel or reactor materials) undergoes a variety of chemical processes leading to enhancement with respect to both the total concentration and chemical purity of the produced uranium compounds.

2021-8-16 · Copper ore enrichment involves mechanical processing which enables an effective management of the extracted ore. As a result, the concentrate contains the amount of copper that can be processed further in a smelter. This process is necessary due to an average 1.52% content of copper in the exploited Polish deposits.

Enrichment. Natural uranium has too low a concentration of uranium-235 (its reactive isotope) for light water reactors. For these reactors, uranium enrichment increases the U-235 concentration from 0.7 per cent to about three to five per cent. Enrichment involves separation of the lighter U-235 atoms from the heavier and more common U-238 atoms.
