PROBLEM TO BE SOLVED: To separate and recover a metal from a metal-containing material easily and quickly and safely, and to separate and recover each component with high selectivity, high yield and continuous separation from each other, and separation of the metal Provide a collection method. A first step of extracting a target metal by bringing a metal-containing material into contact with a supercritical fluid or liquid (particularly preferably, supercritical carbon dioxide), and the metal-containing extract is simulated moving bed type separation. This is achieved by a metal separation / recovery device and a separation / recovery method that pass through a second step of separation by means. In the first step, it is preferable to contact the supercritical fluid or liquid with the complexing agent and the oxidizing agent. [Selection] Figure 1 |
