A device for producing fluorine gas has a first flow path configured to send a fluid from the inside of an electrolytic cell through a mist removal unit configured to remove mist from the fluid to a fluorine gas selection unit and a second flow path configured to send the fluid from the inside of the electrolytic cell to the fluorine gas selection unit without passing through the mist removal unit and has a flow path switching unit configured to switch a flow path through which the fluid flows depending on the average particle size of the mist measured by an average particle size measurement unit. The second flow path has a clogging suppression mechanism configured to suppress clogging of the second flow path by the mist.

The present invention relates to a method for producing a hexafluoromanganate(IV), said method being characterized by comprising: inserting an anode and a cathode into a reaction solution that contains a compound containing manganese having an atomic valence of less than 4 and/or manganese having an atomic valence of more than 4 and hydrogen fluoride; and then applying an electric current having an electric current density of 100 to 1000 A/m.sup.2 between the anode and the cathode. According to the present invention, it becomes possible to produce a hexafluoromanganate(IV) in which the content ratio of manganese having an atomic valence of 4 is high and the contamination with oxygen is reduced and which has high purity. When a complex fluoride red phosphor is produced using the hexafluoromanganate(IV) as a raw material, the phosphor produced has high luminescence properties, particularly high internal quantum efficiency.

A galvanic cell and methods of using the galvanic cell is described for the recovery of uranium from used nuclear fuel according to an electrofluorination process. The galvanic cell requires no input energy and can utilize relatively benign gaseous fluorinating agents. Uranium can be recovered from used nuclear fuel in the form of gaseous uranium compound such as uranium hexafluoride, which can then be converted to metallic uranium or UO.sub.2 and processed according to known methodology to form a useful product, e.g., fuel pellets for use in a commercial energy production system.
