METHODS FOR PRODUCING CAESIUM HYDROXIDE SOLUTIONS

摘要

The invention relates to methods for producing caesium hydroxide solutions during which: caesium-containing ore is disintegrated with sulfuric acid while forming a caesium aluminum sulfate hydrate (caesium alum), which is poorly soluble at low temperatures; the formed caesium alum is separated away in the form of a caesium alum solution from the solid ore residues; aluminum is precipitated out of the caesium alum solution while forming a caesium sulfate solution; the formed caesium sulfate solution is reacted with barium hydroxide or strontium hydroxide while forming a caesium hydroxide solution, and; the formed caesium hydroxide solution is concentrated and purified.
