摘要：A method of producing a higher purity metal comprising the step ofelectrolyzing a coarse metal material by a primary electrolysis to obtain a primaryelectrodeposited metal, the step of electrolyzing the material with the primary

electrodeposited metal obtained in the primary electrolysis step used as an anode toobtain a higher purity electrolyte for secondary electrolysis, and the step of furtherperforming secondary electrolysis by employing higher purity electrolytic solution thansaid electrolytic solution with said primary electrodeposited metal as an anode, wherebyproviding an electro-refining method that effectively uses electrodes and an electrolyteproduced in a plurality of electro-refining steps, reuses the flow of an electrolyte in thesystem, reduces organic matter-caused oxygen content, and can effectively produce ahigh purity metal.
