Abstract
Provided is a method for producing metal by molten salt electrolysis, by which the metal can be efficiently produced. A method for producing metal by using an apparatus for molten salt electrolysis having an electrolytic cell and an electrode pair, wherein the molten salt electrolysis in the electrolytic cell and heating of the molten salt by a Joule heat generation between a pair of electrodes for electrolysis are simultaneously performed; and wherein the apparatus for molten salt electrolysis has at least two sets of electrode pair, and at least one set of the electrode pairs is electrically opened.
Claims6
A method for producing metal by using an apparatus for molten salt electrolysis having an electrolytic cell and at least two electrode pairs, wherein the molten salt electrolysis in the electrolytic cell and heating of the molten salt by Joule heat generated by a pair of electrodes for electrolysis of the at least two electrode pairs are simultaneously performed;
- wherein at least one electrode pair of the at least two electrode pairs is electrically opened, and wherein the at least one electrically opened electrode pair is connected after the molten salt in the electrolytic cell is completely kept in the molten state.
