PROBLEM TO BE SOLVED: To provide an operation method for electrolytic refining equipment, in which a replacement work is carried out in a short time and the operation efficiency is improved.SOLUTION: An operation method for electrolytic refining equipment is provided for a replacement work that is carried out for a time between energization periods in a group A composed of a plurality of electrolytic cells where application and interruption of an electric power are controlled in common. The operation method includes: a discharge step of discharging an electrolytic solution in the electrolytic cells 1a to 1r belonging to the group A; and a solution supply step of supplying the electrolytic solution to the electrolytic cells 1a to 1r belonging to the group A after the discharge step. In the solution supply step, when the electrolytic solution is supplied to the electrolytic cell 1r, the electrolytic solution from a solution supply means 6 provided in the electrolytic cell 1r is supplied, and in addition, the electrolytic solution supplied from the other electrolytic cell 1a is supplied. Thereby, the supply amount of the electrolytic solution to the electrolytic cell 1r is increased and the supply time of the electrolytic solution is shortened, and the temperature rise of the electrolytic solution is hastened. Further, the energization can be fast started while reducing short rate, and the replacement work can be carried out in a short time, and thereby, the operation efficiency is improved. |
