    Uranium milling After mining uranium ore is transported to a nearby mill for processing. The first step is to crush the ore and mix it with water so that it can move through a series of mill circuits. After crushing the ore is treated with acid in large tanks to separate the uranium from other minerals in the rock. The uranium is now part of a liquid solution which is then separated from

  • How is uranium made into nuclear fuelWorld Nuclear

    The vast majority of nuclear power reactors use the isotope uranium-235 as fuel however it only makes up 0.7 of the natural uranium mined and must therefore be increased through a process called enrichment. This increases the uranium-235 concentration from 0.7 to between 3 and 5 which is the level used in most reactors.
