Abstract

The invention belongs to the technical field of copper electrolysis smelting, and particularly relates to a device and method of industrially carrying out magnetized copper electrolysis. The device comprises a permanent magnet device, a transition tank, an electrolytic tank, a low tank, an elevated tank and a steam heating device. According to the device and method, the large-scale and high-efficiency utilization of the copper magnetic electrolysis technology is achieved by the bypass cycle of a magnetic treatment device, and the magnetic treatment efficiency can be improved in the mode that an electrolyte passes through the permanent magnet device at the high speed. The loren magnetic force borne by the electrolyte in the process that the electrolyte passes through the magnetic field canbe enhanced, the electrolyte is greatly activated, the impurity flocculating setting is reinforced, the clarity of the electrolyte is improved, cathode copper crystal grains are refined, the number ofbubbles in the electrolyte is reduced, and the problem that due to the facts that the air bubbles in the electrolyte are prone to having a reaction on the surface of an anode to generate an oxide film, and anodic passivation happens, the cathode copper quality is affected is solved.

Description

technical field [0001] The invention belongs to the technical field of copper electrolytic smelting, and in particular relates to a device and method for industrially implementing magnetized copper electrolysis. Background technique [0002] Electrolytic refining is an important step in the processing and production of copper smelting enterprises, and it is also the basic procedure for the production and manufacture of cathode copper. In recent years, a lot of research has been done on the magnetoelectrolysis process of copper, but it is mainly focused on applying a magnetic field on both sides of the cathode and anode. Although the effect is remarkable, it is difficult to implement industrial production, so that the magnetoelectrolysis process is mainly concentrated in the laboratory. It greatly limits the further development of the magnetoelectrolysis process. For example, the literature [V.C. Noninski. Magnetic field effect on copper electrodeposition in the Tafel potenti...
