ABSTRACT:
Cesium is recovered from cesium alum, CsAl(SO.sub.4).sub.2, by an aqueous conversion and precipitation reaction using a critical stoichiometric excess of a water-soluble permanganate to form solid cesium permanganate (CsMnO.sub.4) free from cesium alum. The other metal salts remain in solution, providing the final pH does not cause hydroxides of aluminum or iron to form. The precipitate is separated from the residual solution to obtain CsMnO.sub.4 of high purity.
