Embodiment 1
[0033] Firstly, the concentration of copper ions in the electrolyte is measured to be 50g / L, and the H 2 SO 4 The concentration is 180g / L, the magnetic field strength of the permanent magnet device 1 is 4T, the first circulation pump 3 is off, and 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, and then Adjust the valve 6 so that the flow rate of the flow meter 5 is displayed as 0.25m / s, then open the first circulation pump 3, so that the flow rate of the bypass circulation system is 0.5 m / s, and simultaneously place the copper anode and the initial plate in the electrolytic cell 4 , set the voltage of electrolytic cell 4 to 0.35V, and the current density: 280A / m 2 , turn on the DC power supply to start electrolysis, and add hydrochloric acid, thiourea, and gelatin dropwise to the electrolytic cell 4 according to the amount of gelatin: 35g / t, thiourea: 35g / t, hydrochloric acid:...
