Title: METHOD FOR REFINING METAL BY USING ELECTROLYTIC REDUCTION AND ELECTROLYTIC REFINING PROCESSES
Abstract:
According to the present invention, a method for refining a metal comprises: an electrolytic reduction step of manufacturing, through electrolytic reduction using a first metal, which is the metal of a binary metal oxide and a metal anode having a eutectic point, an alloy of the first metal and a second metal, which is the metal of the liquid metal anode; and an electrolytic refining step of recovering the first metal from the alloy by electrolytically refining the solidified alloy.
