Title:
METHOD FOR SETTING ELECTROLYTIC REDUCTION CONDITIONS OF METAL AND METHOD FOR ELECTROLYTIC REDUCTION OF RARE-EARTH METAL USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/056717
Kind Code:
A9
Abstract:
An embodiment of the present invention relates to a method for electrolytic reduction of a rare-earth metal through a method for setting electrolytic reduction conditions at the time of electrolytic reduction of a metal from a raw material comprising metal components using an electrolytic bath comprising a cathode and an anode and a supporting electrolyte. The present invention can provide: a method for determining in advance the contact area and the amount of a supporting electrolyte in order to obtain desired current density; and a method for determining in advance the additional input rate of a raw material, and through these methods, the present invention can provide the optimal electrolysis temperature and current density ranges at the time of electrolytic reduction of a metal and promote the improvement of current efficiency.
