A novel extraction process to recover lithium ions from simulated salt lake brines with high Mg/Li ratio was developed. Tributyl phosphate (TBP), FeCl 3 and diethyl succinate were used as extractant, co-extraction agent and diluent, respectively. Effects of extraction conditions containing the volume concentration of TBP, Fe/Li molar ratio and O/A phase ratio on extraction performances were studied. The highest one-stage extraction efficiency of lithium ions and separation factor were about 65% and 350, respectively. In addition, the third phase did not appear over all the volume concentrations of TBP. HCl + MgCl 2 and HCl + NaCl were used as washing and stripping agents, respectively. Effects of washing and stripping conditions on washing and stripping performances were investigated too. Mg(OH) 2 and MgCO 3 were used as regeneration agents to regenerate the organic phase. The extraction efficiency of lithium ions remained at about 53% during reusing the organic phase ten times, demonstrating that the proposed extraction system had good stability and reusability. • A new separation process to extract lithium ions from salt lake brines was developed. • Diethyl succinate used as diluent could effectively eliminate the third phase. • Mg(OH) 2 and MgCO 3 used as regeneration agents showed excellent regeneration ability. • The proposed novel extraction system showed good stability and reusability.
