|a Selective recovery of valuable metals (Cu(2+), Co(2+) and Li(+)) from leachate of spent lithium-ion (Li-ion) batteries was investigated in acidic chloride media using solvent impregnated resins (SIRs). An SIR containing bis(2-ethylhexyl) phosphoric acid (D2EHPA) had high selectivity for Fe(3+) and Al(3+), with an order of selectivity Fe(3+) > Al(3+) > Cu(2+) > Co(2+). Fe(3+) and Al(3+) could be removed from synthetic leachate by precipitation, followed by column adsorption with the SIR containing D2EHPA. The synthetic leachate was then applied to chromatography for selective recovery of Cu(2+), Co(2+) and Li(+). The solution was first fed upward to a column packed with an SIR containing 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester (PC-88A) for selective separation of Cu(2+), followed by upward feed to another column packed with an SIR comprising PC-88A and bis(2,4,4-trimethylpentyl) phosphinic acid (Cyanex 272) for selective recovery of Co(2+). Finally, a column packed with a synergistic SIR containing both 1-phenyl-1,3-tetradecanedione (C11phbetaDK) and tri-n-octylphosphine oxide (TOPO) was used for selective recovery of Li(+). A process flowsheet is proposed for selective recovery of Cu(2+), Co(2+) and Li(+) using several SIRs. This process was found to be simple and efficient for selective recovery of valuable metals from leachate of spent Li-ion batteries. Pure copper, cobalt and lithium products were obtained, with high elution yields
