PCT No. PCT/EP78/00003 Sec. 371 Date Feb. 28, 1979 Sec. 102(e) Date Feb. 28, 1979 PCT Filed Jun. 30, 1978 PCT Pub. No. WO79/00025 PCT Pub. Date Jan. 25, 1979.The invention relates to a process and apparatus for the separation of the isotopes of a body, and particularly of a heavy metal. The process comprises the preparation of a tension-active compound of said body, the solution of this compound in a liquid having a strong surface tension, the injection of a non-miscible body into this solution to form a plurality of separation surfaces, and the recovery of the fraction of the solution adjacent to said separation surfaces. The apparatus comprises a plurality of vats, means for injecting a gas into these vats to produce a foam, means to collect the foam and transfer it into a vat downstream, and means to transfer a portion of the liquid from one vat into another vat located upstream thereof. The process and apparatus are applied to the isotopic separation of uranium.
