| Zusammenfassung: | A method for recovering high-purity lithium carbonate from a solution containing lithium according to the present invention comprises the following steps: (a) cooling the solution containing lithium, and filtering the solution to obtain lithium residual solution; and (b) putting sodium carbonate (Na_2CO_3) into the lithium residual solution of step (a), and heating the solution to recover lithium carbonate (Li_2CO_3). By using the method for recovering high-purity lithium carbonate from a solution containing lithium according to the present invention, high-purity lithium carbonate having a purity of 95-99.8% can be provided, which is recovered from the solution containing lithium.
본 발명에 의한 리튬 함유 용액으로부터 고순도의 탄산리튬 회수방법은, (a) 리튬 함유 용액을 냉각하고 여과하여 리튬 잔류 용액을 수득하는 단계; 및 (b) 상기 (a) 단계의 리튬 잔류 용액에 탄산나트륨(NaCO)을 투입한 후 가열하여 탄산리튬(LiCO)을 회수하는 단계;를 포함하는 것을 특징으로 한다. 본 발명에 의한 리튬 함유 용액으로부터 고순도의 탄산리튬 회수방법을 이용하면, 리튬 함유 용액에서 회수된 탄산리튬의 순도가 95% 내지 99.8%의 고순도의 탄산리튬을 제공할 수 있다. |
