Author: Subject: Recovery of Cesium salts from Pollucite ore.

2006-2-6 · Recovery of Cesium salts from Pollucite ore. Cesium salts are expensive and that is the limiting factor to my involvement with this alkali metal. But I found a simple method to extract relatively high purity cesium salt from its chief ore pollucite. If only I had a source for pollucite, might have to go rock hunting, but I digress.
