Abstract:
It is provided a method for gently and safely recovering only sodium metal from a flux containing sodium metal in a short time and in a reusable form. Flux 23 is heated in a medium 19 unreactive with sodium metal 22 at a temperature equal to or higher than the melting point of sodium metal to separate and recover the sodium metal 22 from the flux 23. The medium is a hydrocarbon, for example.
