Title:
QUALITY CONTROL METHOD FOR ELECTROLYTICALLY REFINING METAL
Document Type and Number:
Japanese Patent JP2783027
Kind Code:
B2
Abstract:
PURPOSE: To provide a quality control method capable of relatively easily judging whether a cathode plate is good or bad, capable of being easily mechanized or automated and also used for improving the electrolytic operation.
CONSTITUTION: The quality is judged from the average current density of a cathode calculated from the weight of a cathode plate or the weight difference between the cathode plates before and after electrolysis and electrolyzing time, and the current distribution in the succeeding stage is uniformized to conduct electrolysis.
