Embodiment 1
[0055] Add 907.9g of nickel chloride, 130g of cobalt chloride, 134g of manganese chloride, 47.3g of magnesium chloride, and 48g of aluminum chloride into 3200mL of water and mix thoroughly, add 3.8g of citric acid (H 2 C 2 o 4 ) was stirred for 1 hour, then purified in a strong magnetic box-type filter to obtain an intermediate liquid, and 30% sodium hydroxide solution was purified in a strong magnetic box-type filter to obtain an alkaline precipitant, and the intermediate liquid was obtained by At a speed of 1.6 liters / hour, the alkaline precipitant is dispersed at a speed of 0.8 liters / hour and enters the non-magnetic reactor at the same time, and the reaction temperature is controlled at 80°C in a liquid-phase environment with both axial flow and radial flow. The pH value is 10.8-10.2, which makes nickel, cobalt, manganese, aluminum, and magnesium ions undergo affinity co-precipitation through hydroxyl bonds. After affinity co-precipitation, they are reconstructed and modi...
Embodiment 2
[0057] Add 972.7g of nickel chloride, 130g of cobalt sulfate, 134g of manganese chloride, 23.5g of magnesium chloride, and 24.1g of aluminum chloride into 3000mL of water, and then add 3.2g of citric acid with a weight ratio of 2:1 (C 6 h 8 o 7 ), oxalic acid (H 2 C 2 o 4 ) mixture was stirred for 2.5 hours, then purified in a non-magnetic box-type filter to obtain an intermediate liquid, and 40% sodium hydroxide solution was purified in a strong magnetic box-type filter to obtain an alkaline precipitant, and the intermediate liquid At a rate of 1.8 liters / hour, the alkaline precipitant is dispersed at a rate of 0.82 liters / hour and simultaneously enters the strong magnetic reactor, and the reaction temperature is controlled at 75°C in a liquid-phase environment with both axial flow and radial flow. The pH value is 10.6-11.1, so that nickel, cobalt, manganese, aluminum, and magnesium ions are co-precipitated through the affinity co-precipitation of hydroxyl bonds. After th...
Embodiment 3
[0059] Add 1011.6g of nickel chloride, 130g of cobalt chloride, 134g of manganese chloride, 9.2g of magnesium chloride, and 9.8g of aluminum chloride into 3900mL of water, mix well, add 3.2g of citric acid (C 6 h 8 o 7 ) was stirred for 2.5 hours, then purified in a non-magnetic box-type filter to obtain an intermediate liquid, and 40% sodium hydroxide solution was purified in a strong magnetic box-type filter to obtain an alkaline precipitant, and the intermediate liquid was obtained by At a speed of 1.5 liters / hour, the alkaline precipitant is dispersed at a speed of 0.6 liters / hour and enters the strong magnetic reactor at the same time, and the reaction temperature is controlled at 65°C in a liquid phase environment with both axial flow and radial flow. The pH value is 13.5-114, which makes nickel, cobalt, manganese, aluminum, and magnesium ions pass through the affinity co-precipitation of hydroxyl bonds. After the affinity co-precipitation, it is reconstructed and modif...
