| titleOfInvention | Method for preparing cobalt carbonate |
| abstract | The invention provides a method for preparing cobalt carbonate, which comprises the following steps: s1, adding a cobalt salt solution and an ammonium bicarbonate solution into the seed crystal kettle, reacting for 20-30h, and increasing the flow of the cobalt salt solution by 20-40L/h every 15-20h until obtaining cobalt carbonate seed crystals with the particle size D50 of 11.5-14.0 μm; s2, adding cobalt carbonate seed crystals into the finished product kettle, and adding a cobalt salt solution and an ammonium bicarbonate solution into the finished product kettle; s3, after reacting for 15-20h, increasing the flow of the cobalt salt solution in the S2 by 40-60L/h until the tap density is 2.5-2.8g/cm 3 The cobalt carbonate finished product. The flow of the cobalt salt solution is controlled at different time periods, so that the process of preparing the cobalt carbonate is smoothly carried out, and more cobalt carbonate crystal seeds and cobalt carbonate finished products which accord with the morphological characteristics are obtained; and the cobalt carbonate finished product is prepared by using the cobalt carbonate seed crystal, so that the yield and the efficiency of preparing the cobalt carbonate finished product are improved. |
