ELECTROLYTIC REFINING METHOD AND ELECTROLYTIC CELL

摘要

PROBLEM TO BE SOLVED: To obtain a refined material having little protuberance on a surface and small impurity content by electrolytic refining as the refined material obtained by electrodeposition. SOLUTION: In an electrolytic refining method which refines a material to be refined deposited to an anode plate 30 in an electrolytic soln. by electrolyzing the material to electrodeposit the material on a seed plate cathode 20, the anode plate 30 and the seed plate cathode 20 are hung in an electrolytic bath 10 storing the electrolytic soln. so as to be dipped into the electrolytic soln. and electrolytic refining is executed. In this case, space between a lower end of the hung seed plate cathode 20 and a bottom surface of the electrolytic bath 10 is made to be∞450 mm and electrolytic refining is executed.
