Embodiment 1

[0033]First, the concentration of copper ions in the electrolytic solution is 50 g / L, h2SO4The concentration of 180 g / L, the magnetic field strength of the permanent magnet device 1 is 4T, the first circulation pump 3 is closed, then the second circulation pump 8 and the steam heating device 10 are turned on, so that the temperature of the electrolyte is controlled at 65 ° C, then The regulating valve 6 causes the flow rate of the flow meter 5 to be 0.25m / s, and then turn on the first circulation pump 3 so that the flow rate of the bypass circulation system is 0.5 m / s, and the copper anode and the beam piece are placed in the electrolytic cell 4. In the middle, the voltage of the electrolysis slot 4 is 0.35V, current density: 280A / m2Open the DC power supply to start electrolysis, at the same time according to gelatin: 35 g / t, thiourea: 35 g / t, hydrochloric acid: 150 g / t (t to T, cathode copper per ton), add hydrochloric acid, thiourea, gelatin. After the electrolytic...

Abstract

The invention belongs to the technical field of copper electrolysis, and specifically relates to a device and method for industrially implementing magnetized copper electrolysis, including a permanent magnet device, a transition tank, an electrolytic tank, a lower tank, a higher tank and a steam heating device. The bypass circulation of the treatment device realizes the large-scale and high-efficiency utilization of the magnetoelectrolysis process of copper, and the magnetic treatment efficiency can be improved by passing the electrolyte at high speed through the permanent magnet device; the invention can enhance the Loren Magnetic force greatly activates the electrolyte, strengthens the flocculation and sedimentation of impurities, improves the clarity of the electrolyte, refines the cathode copper grains, reduces the number of bubbles in the electrolyte, and solves the problem that the air bubbles in the electrolyte are easy to react on the surface of the anode to form an oxide film Anode passivation affects the quality of cathode copper.

Description

Technical field[0001]The present invention belongs to the field of copper electrolyte smelting, and in particular 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 is also a basic procedure for cathode copper production. In recent years, the magneto-electrolysis process related to copper has been studied, but it is mainly concentrated on implying a magnetic field on both sides of the yin and influence, but it is difficult to implement industrial production, so that the magnetoal electrolysis process is mainly concentrated in the laboratory. It is greatly limited to the development of magneto-electrolysis processes, for example, literature [VC Noninski. MagneTic Field Effecton Copper ElectrodePosition in The Tafel Potential Region [J]. ElectrochimicaActa, 1997,42 (2).] Found that the magnetic field can improve the ...
