    This is referred to as processing, and the result is a yellow paste known as "yellow cake", which contains 75% of uranium oxide. The "yellow cake" is then purified by a series of chemical transformations and converted into a fluorinated form (UF6: 6 fluorine atoms for one uranium atom). This is called the "conversion" operation.
