Each isotope has a characteristic mass that is distint from the mass of any other isotope. An isotope with a lower mass difuses more rapidly than one with a higher mass. Although the difference is usually small,many sequential diffusion stages can result in an almost pure sample of one isotope. This was the method by which the uranium-235 isotope in natural uranium was sufficiently concentrated to make the first atomic bomb.
Uranium 235 is a natural isotope of uranium (the concentration is approx. 0,7 %); uranium 235 is separated from the other uranium isotopes by different methods (centrifugation, gaseous diffusion;also on small scale by laser, mass spectrometric, ion exchange, etc.).

Helium is gaseous but it is not a mixture - it is a chemical element.
Neon
fluorine
The gaseous diffusion separation of the uranium isotopes is very efficient but expensive; the centrifugation is now preferred.

Radon is the densest gaseous element.
The gaseous element is oxygen.

There are several ways in which elements can be separated by physical methods. Centrifuge If you grind an ore to sufficient fineness, you can use a centrifuge to separate an element based on its specific gravity. Panning is a more primitive version of this basic method. Gaseous Diffusion You can also heat an ore to the temperature at which a particular element becomes gaseous and separate it out.
Solid state diffusion (between metals) and gaseous diffusion (a gas in a metal).
