ABSTRACT:
Cesium is recovered from a cesium-bearing mineral such as pollucite by roasting with an alkaline flux to convert the cesium to a soluble salt, extracting the cesium salt with water, and separating the cesium solution from the residual solids. Water-soluble permanganate is then added to the cesium solution to selectively precipitate cesium permanganate, giving other soluble metal compounds in solution. Cesium permanganate of high purity is recovered by separation from the residual solution. The cesium permanganate can be converted to other cesium compounds.
