Abstract

The solvent extraction of Fe(III), Co(II), Cu(II), Zn(II) impurities from chloride-sulfate nickel solutions by individual extractants and mixtures based on a tertiary amine has been studied. Using an example of the extraction of cobalt(II), the influence of the type of modifier, concentration of the extractant, nature of the diluent for the extraction of impurities was determined. A technological scheme for the purification of nickel solutions from impurities was developed.
