Study on Preparation of Lithium Carbonate from Lithium-containing Residue AITranslate
Abstract AITranslate
To overcome the problem of inadequate utilization of Li resource in lithium-containing residue, Li2CO3 was prepared from lithium-containing residue by H2SO4 leaching, NaOH purification and EDTA deeply purification, and lithium precipitation with Na2 CO3. The results show that the optimal technological parameters are as follows： in the process of H2SO4 leaching, H2SO4 concentration of 5% （volume frac- tion） ,leaching temperature of 70 ℃ ,and leaching time of 60 min. In the process of NaOH purification and EDTA deeply purification,end pH of NaOH addition of 12 ,EDTA addition of 2.0 g/L;in the process of Li precipitation with Na2CO3 ,Li＋ concentration of 23 g/L in solution,Na2CO3 concentration of 300 g/L,and Na2CO3 dosage of 1. 10 times of the theoretical quantity, bath temperature of 95 ℃,reaction time of 40 min. With the optimal technological parameters, the indexes of Li2 CO3 products basically meet the require- ments of Li2CO3-0 level,and the comprehensive recovery rate of Li is over 95%.
