Uranium Yellow Cake

Yellowcake uranium the powdered typically yellow form of uranium oxide with the chemical formula U3O8. In the nuclear fuel cycle, yellowcake is a product of the second step, occurring directly after mining and is created through milling. After the uranium is mined, the ore that is obtained has many different complex uranium oxides within it. The ore is therefore reduced (milling process) to one specific oxide, U3O8, in order to be converted into uranium hexafluoride, UF6, which is the third step in the nuclear fuel cycle.
