Selective removal of iron(III) from highly salted chloride acidic solutions by solvent extraction using

Guoping Hu, Yue Wu, Desheng Chen, Yong Wang, Tao Qi, Lina Wang

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.
