Definition from
European Nuclear Society:
Yellow cake is the final product of the milling of uranium ore. It contains about 80 % of uranium oxide and is usually represented by the formula U3O8. The yellow cake produced by most modern mills is actually brown or black, not yellow; the name comes from the colour and texture of the concentrates produced by early mining operations due to impurities from ammonium diuranate (NH4)2U2O7.
Example sentences:
The solvents are removed by evaporating in a vacuum and ammonium diuranate, (NH4)2U2O7, is precipitated by adding ammonia to neutralize the solution. The diuranate is then heated to yield a purified, solid U3O8, known as yellow cake. (Kennesaw State University )
On site, close to the mines, the uranium is concentrated and transformed into a yellow powder, commonly called yellow cake, which contains 75% of uranium. It is in this form that the uranium is marketed. (planete-energies.com)
The first stage of this process is to dissolve the yellow cake in nitric acid; solvent extraction using tributyl phosphate in a hydrocarbon solution extracts the uranium from the various impurities and then the extract is washed with dilute nitric acid to produce uranyl nitrate in a very pure form.

Definition from
own experience or research:
Yellowcake is concentrated uranium oxide, obtained through the milling of uranium ore.<br />Uranium oxide<br />Uranium oxide is an oxide of the element uranium. <br />The metal uranium forms several oxides: <br />• Uranium dioxide or uranium(IV) oxide (UO2, the mineral Uraninite or pitchblende)<br />• Uranium trioxide or uranium(VI) oxide (UO3)<br />• Triuranium octaoxide (U3O8, the mineral uranite, the most stable uranium oxide)<br />Uranium dioxide is oxidized in contact with oxygen to the triuranium octaoxide.
