Abstract

An extraction technology for purification of manganese sulfate solutions from Ca, Mg and Na using di(2,4,4-trimethylpentyl)phosphinic acid in a diluent (Cyanex 600) as an extractant has been developed. The created technology allows obtaining manganese sulfate monohydrate suitable for the production of lithium-ion batteries. The developed technology surpasses the technology previously created with Cyanex 272 in technological parameters [1]
