Abstract

Studies on the extraction recovery of Fe(III), Co(II), Cu(II), and Zn(II) impurities with individual extragents and tertiary amine mixtures from nickel chloride–sulfate solutions are carried out. Using cobalt(II) extraction as an example, the effect of the modifier type, extragent concentration, and dilutant nature on the extraction of impurities is established. A process layout for the purification of nickel solutions from impurities is developed.
