processing cesium ore - ombrelle-parapluie.ch
A Zeolite ion-exchange process was developed and used on the Hanford Atomic Energy Project for the separation of radioactive cesium from highly radioactive liquid wastes (Mercer and Ames 1976). The waste had developed high cesium content from filtering liquid waste and a system was developed to back-exchange the cesium for re-use.
THE REACTION BETWEEN CESIUM AND CARBON DIOXIDE …
The reaction between cesium and carbon dioxide gives a product of the formula Cs/sub 2/CO/sub 2/, which appears to be ''cesium cesioformate'' or CsCOOCs.
