[Problem] molten salt electrolysis of a molten salt electrolytic device retains stored inside, rare earth metal or iron alloy such as fused salt electrolysis of the liquid composition, is not oxidized, using electrolytic recovery by sucking from the suction nozzle, and a device for performing this method. [Solution] the method of the invention, a non-oxidizing atmosphere and the pressure within the suction chamber can be connected, after the tip end of the nozzle opening can be sealed with a sealing member, and the opening is then immersed in an electrolytic bath, a non-oxidizing atmosphere at a pressure within the suction chamber, electrolysis of the liquid accumulated in the molten salt electrolyte composition, using a suction nozzle and suction chambers in suction recovery. The device of the invention, the method of the invention for collecting chamber being provided with at least a suction nozzle. Figure 2 [drawing]
