Process for recovering cesium from pollucite

In one process which has undergone considerable development for commercial use, ground pollucite ore is leached with strong sulfuric acid to obtain an extract containing cesium alum, which is recovered by crystallization for further processing. The cesium alum process has been considered a traditional process for recovering cesium from pollucite.

All Moon Ores

When chunks of ore mined out of moons yield above-average densities of Pollucite, the ore is called Replete Pollucite and reprocessing returns approximately 15% higher quantities of useful material. A rare ore commercially mined from moons, Pollucite is valuable as it yields good quantities of Caesium, a key element of many advanced materials.
