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

уранов концентрат U3O8


Definition from own experience or research:
Урановият концентрат U3O8 е продукт, получаван при преработването на урановата руда, който се характеризира с високо съдържание на уранов оксид U3O8.

Example sentence(s):
  • Добив на уранови и ториеви руди и техните концентрати. Включва: - добив на уранови и ториеви руди - обогатяване на тези руди - производство на уранови концентрати (yellowcake) - NSI - НАЦИОНАЛЕН СТАТИС�  
  • Уранът се добива от рудата чрез киселина. Продуктът от този процес, след като се преработи отново, е жълт концентрат. - Климат  
  • Производствени проблеми и недостиг вдигнаха цените на концентрата на уранов оксид U3O8 близо 10 пъти през последните шест години. - КАПИТАЛ  

Explanation:
* Урановият концентрат U3O8 (или концентрат на уранов оксид U3O8), като продукт от преработването на урановата руда, се нарича още “жълт кек” или “жълт кейк” (yellow cake) заради жълтия цвят, който първоначално е бил характерен за продукта.
* Пълното наименование на урановия оксид U3O8 е "триуранов осмоокис" или, според по-новата класификация, "триуранов октаоксид".
