PROCESS FOR STOPPING AND RESTARTING AN ELECTROLYTIC REFINING PLANT

摘要

ABSTRACT OF THE DISCLOSURE: A method for making a more or less prolonged shutdowns and restarts, series of copper electrorefining tanks. The process of preparing the judgment by decreasing the content of the electrolyte Cu 2+ ions, controlling admixtures, adjusting the level of the electrolyte, slow crystallization of CuSO4 in the form of very fine crystals; subsequent restarts includes a recirculation of the electrolyte with gradual warming, gradual increase in the intensity electrolysis, and recovery of the additive intake. The implementation of the invention allows to obtain refined copper deposits of commercial quality from the first electrolysis cycle.
