Depleted uranium is a by-product of the production of enriched uranium for use in nuclear reactors. Although very low in radioactivity, depleted uranium must be physically protected and may be subjected to international safeguards. Commercially, depleted uranium is used in medicine, space, aviation and petroleum exploration.

By November 2022, Iran was operating 1,044 IR-2m centrifuges and 348 IR-4 centrifuges to produce and stockpile low-enriched uranium at the FEP at Natanz. It was also using a …
At the mill, uranium ore undergoes a variety of changes to turn it into a finished product: uranium powder, also known as yellowcake.. The milling process is so important that the U.S. Atomic Energy Commission has helped mines establish mills close by to make it easier to process uranium ore and quicken the production of yellowcake [source: Amundson].

Annual production rates between 34 and 113 kg (net uranium) can be achieved with one 164-machine cascade using P1-type technology. In addition to the the steady-state results for this cascade and the various machine-types, the transient response of the system to changes in the feed rate or feed enrichment (e.g., batch-recycling mode) is of ...

Normally approximately 95 - 98% of the uranium can be recovered from the host rock. From this acid or alkaline solution, uranium oxide or yellowcake is precipitated. This is still not the purest form, and the uranium has to be sent to another plant to enrich it. The remaining rock slurry is pumped to a tailings dam.
