Abstract: A method for separating barium contaminants from soluble strontium compounds comprising adding sulfuric acid and a basic strontium compound in solid, suspended or dissolved form to an aqueous solution of a barium-contaminated soluble strontium compound in controlled amounts with thorough stirring to maintain the pH of the solution between about 3 and about 10; removing solids which precipitate from the solution; and thereafter recovering a strontium compound having a decreased barium content from the solution. The method may be carried out continuously or batch-wise, and the sulfuric acid and basic strontium compound can be added in repeated alternating portions or continuously.
