| Abstract: | As to the technology of producing Li 2CO 3 by the method of carbonas precipitation,using additives for controlling crystallization process of KCl (impurity substance) in the feed liquid system,We can separate it by crystalization form the system more completely before the precipitation of Li 2CO 3,thus it can purity the feed liquid and improve the quality of the end production.The compound additive which is composed of KMnO 4 and K 2CO 3 found out in the experiment can accelerate the growth rate of KCl and make its separating dot preact,so as to attain the purpose of the research. |
