The gaseous diffusion process uses molecular diffusion to separate a gas from a two-gas mixture. The isotopic separation is accomplished by diffusing uranium [which has been combined with fluorine to form uranium hexafluoride (UF 6) gas] through a porous membrane (barrier), and using the different molecular velocities of the two isotopes to achieve separation.

Mining & Milling - Cameco U101

Uranium ore is simply rock with elevated amounts of uranium in it. Once the rock has been removed by open pit or underground mining it must be milled to separate the uranium from other constituents. The milling process for uranium is similar to that used for other metals such as copper, gold or nickel.

Uranium (Nuclear) - need.org

was used, the uranium is already dissolved in solution. The chemical-ore solution undergoes further treatments to separate the uranium as a precipitate. Uranium is collected and dried as uranium oxide (U 3 O 8) concentrate. The concentrate is a powder called yellowcake. This process of removing uranium from the ore is called uranium milling.
