Abstract: Provided is a separation recovery method of metal ions and a two-phase separated fluid. The separation recovery method includes mixing a water phase including two or more kinds of metal ions and an organic compound with an oil phase including an extractant to move metal ions belonging to Group 8 to Group 12 from the water phase to the oil phase, the two or more kinds of metal ions including metal ions belonging to Group 3 to Group 16, and the organic compound coordinated to at least one kind of metal ions among the metal ions. In the two-phase separated fluid, a water phase including two or more kinds of metal ions including metal ions belonging to Group 3 to Group 16 and an organic compound and an oil phase including an extractant are phase-separated and present, and metal ions where the extractant is coordinate-bonded to metal elements belonging to Group 8 to Group 12 are present in the oil phase.
