The composition, preparation methods, and mass transfer mechanisms of ELM (emulsion liquid membrane), SLM (supported liquid membrane), and PIM (polymeric inclusion membrane), and the research progress of these three types of membranes in hydrometallurgy in recent 5 years are reviewed. Additionally, the advantages and disadvantages of the three membranes in hydrometallurgy were summarized, and the solution to the problems such as ELM films exhibited instability and difficulties with emulsion breaking, SLM membranes tended to be unstable with the membrane phase is lost to the water phase and PIM demonstrated lower mass transfer efficiency requiring longer time to reach equilibrium are proposed. Finally, the future development direction for the three membranes in the field of hydrometallurgy are prospected, providing a crucial foundation for further promoting the application of membrane extraction technology in hydrometallurgy and expediting the industrial production of membrane extraction technology.
