摘要：

The present study deals with the carrier-facilitated transport of manganese from this acidic leach solution in an emulsion liquid membrane system. The ELM consists of MDEHPA as the extractant, industrial solvent as the inert diluent, non-ionic polyethylene glycol as a surfactant and sulfuric acid as the stripping solution. The main parameters influencing the ELM stability and the extraction of manganese are the pH of the acidic leach solution, mixing speed, concentrations of the stripping solution, extractant and surfactant, phase ratio and treatment ratio. With respect to the parameters mentioned, the optimum conditions for the process were determined. The results demonstrated the possibility of 93% extraction of manganese by ELM from the acidic leach solutions at optimum operational conditions.
