Abstract

PURPOSE: To remove sulfate ion in extracted phosphoric acid almost completely by maintaining the concentration of phosphoric acid in the extracted phosphoric acid at high level, adding Ba compounds in an amount less than chemical equivalent to sulfate ion contained, and separating formed BaSO4.
