METHOD FOR PRODUCING METAL AND METHOD FOR PRODUCING REFRACTORY METAL

摘要

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.
