| 英文摘要 | Metal ions including Fe~(3+), Ca~(2+),Mg~(2+), Ni~(2+), Co~(2+) and Cu~(2+) are commonly found in the leaching solution oflaterite-nickel ores, and the pre-removal of Fe~(3+) is extremely important for the recovery of nickel and cobalt. Di(2-ethylhexyl)phosphate acid (D2EHPA) showed high extraction rate and selectivity of Fe~(3+) over other metal ions. The acidity of the aqueous solution is crucial to the extraction of Fe~(3+), and the stoichiometry ratio between Fe~(3+) and the extractant is 0.86:1.54. The enthalpy for the extraction of Fe~(3+) using D2EHPA was 19.50 kJ/mol. The extraction of Fe~(3+) 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_2C_2O_4>NH_4HCO_3>HCl>NaCl >NaHCO_3 >Na_2SO_3. The stripping of Fe was ≥99% under the optimized conditions using H_2C_2O_4 as a stripping reagent. |
