WebYellowcake – U3O8. Yellowcake, chemically U3O8, is a uranium concentrate powder recovered from leach solutions. Yellowcake is an intermediate step in processing uranium ores and nuclear fuel production. Typically, yellowcake can be obtained through the conventional milling and chemical processing of uranium ore, forming a coarse powder. WebActually Uranium (the element) IS naturally formed.

WebUranium occurs naturally in several minerals such as uranite (pitchblende), brannerite and carnotite. It is also found in phosphate rock and monazite sands. World production of uranium is about 41,000 tonnes per year. Extracted uranium is converted to the purified oxide, known as yellow-cake. WebThese 'fission tracks' are formed by the spontaneous fission of 238U and are only preserved within insulating materials where the free movement of electrons is restricted. Because the radioactive decay occurs at a known rate, the density of fission tracks for the amount of uranium within a mineral grain can be used to determine its age.
