Abstract
Official abstract text for this publication.
The present invention relates to a method of extracting lithium with high purity from a lithium bearing solution by electrolysis. More specifically, the present invention provides a method of economical extraction of lithium from the lithium bearing solution by adding a phosphorous supplying material to the solution to prepare a lithium phosphate aqueous solution subject to electrolysis.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of extracting high purity lithium from a lithium bearing solution by electrolysis comprising the steps of: preparing a lithium phosphate aqueous solution from the lithium bearing solution by adding a phosphorous supplying material; and extracting lithium from the lithium phosphate aqueous solution by electrolysis using an electrolytic device comprising an anode and a cathode separated from the anode by a cation exchange membrane, wherein the ste…
