Document Type and Number:
WIPO Patent Application WO/2023/210748
Kind Code:
A1
Abstract:
This method for producing high-purity aluminum has a step for disposing an Al crude metal anode and a cathode so as to face each other in a highly electroconductive molten salt, supplying electricity between the Al crude metal anode and the cathode at a temperature at which the Al crude metal anode is solid and the highly electroconductive molten salt is liquid to ionize and elute aluminum from the Al crude metal anode, and depositing an aluminum deposit on the cathode.
