METHOD OF MANUFACTURING HIGH CONCENTRATED LITHIUM CHLORIDE SOLUTION FROM INSOLUBLE LITHIUM COMPOUND AND METHOD OF MANUFACTURING LITHIUM COMPOUND USING THE SAME

摘要

The present invention relates to a method for producing a high concentration of lithium chloride through a hydrothermal reaction between an insoluble lithium compound and a chloride, and a lithium compound (lithium carbonate or hydroxide) through carbonation and/or hydroxide reaction of the high concentration lithium chloride prepared by the above method. lithium). According to the present invention, by using a hydrothermal reaction, a high concentration of lithium solution can be prepared from an insoluble lithium compound by a simple process, and while suppressing the use of an excessive amount of alkali solvent from the high concentration of lithium solution, it is economically carbonated with low energy consumption There is an advantage in that lithium or lithium hydroxide can be prepared.
