Abstract The synergistic solvent extraction (SSX) system consisting of di-2-ethylhexyl phosphoric acid (P204) and alkyl-4-pyridinecarboxylate ester (4PC) in sulfonated kerosene was used to separate manganese from magnesium and calcium and to prepare pure manganese sulfate solutions with battery grade. In batch tests, over 99.9% of Mn2+ was extracted after a four-stage counter current
