Eutectic solvents have excellent characteristics such as low melting point, high solubility and easy preparation, and have attracted extensive attention in the field of hydrometallurgy. As a new “green” solvent, eutectic solvents not only avoid the equipment corrosion problems caused by traditional acid leaching or alkali leaching, but also greatly reduce costs and reduce environmental pollution. In this paper, the composition, classification and physicochemical properties of existing eutectic solvents were comprehensively reviewed, and the research progress of eutectic solvents in the leaching of metal minerals and metal oxides was emphatically introduced, and the future development trend of eutectic solvents was prospected according to the existing problems.
