ABSTRACT:
The invention relates to the application of an electric potential to a mixture of molten metal droplets, molten salts, and optionally certain fluoride salt additives, whereby the molten metal migrates toward one of the electrodes. The migration encourages increased coalescence of the droplets into larger particles, whereby increased recovery of the metal from the mixture is achieved.
