Abstract: Ionic liquids as green solvents have shown important application in the extraction and separation of nonferrous metals. The new and important fundamental and applied research results in extraction and separation of nonferrous metals with ionic liquids, including the dissolution and corrosion of metals and metal oxides, electro-deposition of active metals such as Mg, Al and Ti, and hydrometallurgy of chalcopyrite, are introduced in this paper. It is shown that ionic liquids involved processes can be carried out at or near room temperature, which can significantly lower the energy consumption, operation cost, and pollutant emission.
