A method of extracting high purity lithium phosphate from brine, the method comprising the steps of: precipitating and removing impurities including magnesium, boron, or calcium contained in the brine by adding hydroxide anions to the brine; Injecting a phosphorus supply material to the remaining filtrate after the impurities are removed to precipitate lithium contained in the brine to lithium phosphate; providing a method of extracting high purity lithium phosphate from brine, evaporation of brine for a long time and Without concentration, lithium can be extracted economically with high recovery. |
