Title:
MOLTEN SALT ELECTROREFINING APPARATUS AND REFINING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/107915
Kind Code:
A1
Abstract:
The present invention provides a molten salt electrorefining apparatus comprising: a reaction crucible which is provided inside a reaction vessel and is filled with a molten salt electrolyte; an anode and a cathode immersed in the molten salt electrolyte; an anode crucible in which a liquid raw material alloy is received; a cathode crucible in which at least one raw material metal included in the raw material alloy is recovered in a liquid state; and a heater for controlling the temperature of the molten salt electrolyte to be equal to or higher than the melting temperature of the raw material alloy, and thereby the molten salt electrorefining apparatus can effectively recover high-purity indium by refining the raw material alloy including indium by means of molten salt electrorefining. Also, the present invention provides a molten salt electrorefining method which recovers indium (In) from an indium-tin (In-Sn) alloy by using a molten salt electrolyte including fluoride.
