Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 3,   Pages 528-537 doi: 10.1007/s11705-020-1955-4

Abstract: Metal ions including Fe , Ca , Mg , Ni , Co and Cu are commonly found in the leaching solution of laterite-nickel ores, and the pre-removal of Fe is extremely important for the recovery of nickel and cobalt. Di(2-ethylhexyl)phosphate acid (D2EHPA) showed high extraction rate and selectivity of Fe over other metal ions. The acidity of the aqueous solution is crucial to the extraction of Fe , and the stoichiometry ratio between Fe and the extractant is 0.86:1.54. The enthalpy for the extraction of Fe using D2EHPA was 19.50 kJ/mol. The extraction of Fe was ≥99% under the optimized conditions after a three-stage solvent extraction process. The iron stripping effects of different reagents showed an order of H C O >NH HCO >HCl>NaCl>NaHCO >Na SO . The stripping of Fe was ≥99% under the optimized conditions using H C O as a stripping reagent.
