<P>PROBLEM TO BE SOLVED: To provide a method of producing a metal, capable of stabilizing the concentration of an additive in an electrolytic solution used in electrorefining, and of suitably controlling the operation. <P>SOLUTION: The method of producing a metal is characterized by controlling the amount of the additive 60a to be added into an electrolytic solution 10 for replenishment prior to feeding it into an electrolytic cell 11 so as to control the concentration of the additive 60a present in the electrolytic solution 10 within a predetermined range in the vicinity of a solution feeder through which the electrolytic solution 10 for replenishment with the additive 60a added therein is continuously fed into the electrolytic cell 11, so that the concentration of the additive 60a in the electrolytic solution 10 recovered to an effluent tank 12 from the electrolytic cell 11 does not fall below a predetermined concentration. <P>COPYRIGHT: (C)2013,JPO&INPIT |
