The invention discloses a continuous reaction method for synthesizing large-particle-size cobalt carbonate, which specifically comprises the following steps: respectively preparing a cobalt chloride solution with a concentration of 10-120 g/L and a sodium bicarbonate solution with a concentration of 50-130 g/L, and pumping the prepared cobalt chloride solution into a reaction kettle to serve as abase solution; continuously pumping the cobalt chloride solution into the reaction kettle, heating the solution in the reaction kettle to 50-70 DEG C, pumping the sodium bicarbonate solution into thereaction kettle to adjust the pH value to 5.0-8.5, and stirring the solution in the reaction kettle for reaction; and when the solid content in the solution in the reaction kettle reaches 150-300 g/L,stopping pumping the cobalt chloride solution and the sodium bicarbonate solution, standing and aging the obtained turbid liquid, and conducting filtering, washing and drying to obtain a finished product. According to the proc
