A PROCESS FOR RECOVERING LITHIUM FROM A BRINE.

摘要

There is disclosed herein a process for recovering lithium from an impure natural or industrial brine, the process comprising adjusting the pH of a feed brine containing lithium to a value of no less than 11.3 and separating the waste solids and a solution containing lithium values. The solution may be further concentrated and treated to obtain lithium carbonate and a lithium chloride solution suitable for obtaining electrolytic grade lithium chloride.
