Embodiment 1
[0038] Cobalt chloride solution obtained by hydrometallurgy (Co 2+ :95g / l Cu 2+ :0.0051g / l Fe 2+ :2+ :2+ :2+ :2+ :2+ :0.0018g / l Al 2+ :2+ : 0.0020g / l Mn 2+ : 3 / h m 2 Pump the electrolysis solution into the electrolytic cell, and use a vacuum negative pressure device to maintain a negative pressure of 0.03~0.05MPa inside the system. When the negative pressure in the tank is stable, turn on the power supply and maintain 800A / m 2current density for electrowinning. In the process of electrowinning, the temperature is 30~50℃, and the cell voltage is 2.4~2.8V. During the electrolysis process, the chlorine gas generated by the anode and the liquid after the electrowinning enter the gas-liquid separator together, and the gas is separated through the gas-liquid separator. Liquid separation, the dechlorinated cobalt liquid is returned to the cobalt liquid circulation tank as the pre-electrodeposition liquid, and the obtained vacuum-removed chlorine gas is washed with pure water, d...
Embodiment 2
[0040] Cobalt chloride solution (Co 2+ :100g / l Cu 2+ :2+ :2+ :2+ :0.0008g / l Pb 2+ :2+ : 0.0059g / l Mg 2+ :0.0018g / l Ca 2+ : 0.0016g / l Mn 2+ : 0.00058g / l oil: 4.72 ph=2.3) as the pre-electrodeposition solution, electro-deposit in a closed electrolytic cell. Control flow rate 10~14m 3 / h m 2 Pump the electrolytic solution into the electrolytic cell, and use a vacuum negative pressure device to maintain a negative pressure of 0.06~0.08MPa inside the system and maintain a negative pressure of 800A / m 2 current density for electrowinning. In the process of electrowinning, the temperature is 30~50℃, and the cell voltage is 2.4~2.8V. During the electrolysis process, the chlorine gas generated by the anode and the liquid after the electrowinning enter the gas-liquid separator together, and the gas is separated through the gas-liquid separator.
