A process for continuously separating uranium isotopes, 235U and 238U, by passing a soln. of a mixt. of uranium isotopes in a solvent through a column of an anion exchanger comprises (a) forming in the column a boundary (A) between a uranium adsorption zone and an adjacent reducing agent zone, and a boundary (B) between the adsorption zone and an adjacent oxidizing agent zone, (b) advancing the adsorption zone through the column while effecting the redn. at (A) and effecting the oxdn. at (B) to effect an enrichment of 235U and 238U, and (c) separately collecting fractions enriched in the isotopes. The oxidizing agent is Cr (VI), Mn (VII), Fe (III) or Cu (II), and the reducing agent is Sn (II), Ti(III) or V(III).
