| description | A metal recovery system includes: a desalination apparatus obtaining freshwater with a reverse osmosis membrane from liquid to be processed pressurized by a pump; a metal recovery apparatus recovering metal ions from first drainage from the desalination apparatus, using a metal ion exchange membrane; and a control apparatus that includes: a pump control unit controlling energization of the pump so that an inflow flow rate of the liquid to be processed flowing into the desalination apparatus is a predetermined first flow rate when an exchange membrane temperature is within a temperature range determined in advance; and an exchange membrane control unit controlling energization of electrodes applying an electric field to a metal ion exchange membrane based on a first ion concentration that is a concentration of the metal ions in the first drainage when the exchange membrane temperature is within a temperature range determined in advance. |
