Abstract
Methods for producing cesium hydroxide solutions during which: cesium-containing ore is disintegrated with sulfuric acid while forming a cesium aluminum sulfate hydrate, which is poorly soluble at low temperatures; the formed cesium alum is separated away in the form of a solution from the solid ore residues; the aluminum is precipitated out of the cesium alum solution while forming a cesium sulfate solution; the formed cesium sulfate solution is reacted with barium hydroxide or stontium hydroxide while forming a cesium hydroxide solution, and; the formed cesium hydroxide solution is concentrated and purified.

1-30. (canceled)
A process comprising preparing a cesium hydroxide solution by digesting a quantity of cesium-containing ore with sulfuric acid or forming a cesium aluminum sulfate hydrate which poorly soluble when cold, separating the cesium alum formed from solid ore residues as a solution from the digested ore of cesium alum, precipitating the aluminum from the cesium alum solution to form a cesium sulfate solution, reacting the cesium sulfate solution with barium hydroxide to form a cesium hydroxide solution, and concentrating and purifying the cesium hydroxide solution.
A process according to clam 31, wherein the cesium-containing ore is pollucite.
