English term or phrase: yellow cake
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 sentence(s):
  • 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. landmarkminerals.com
