FIELD: extracting lithium.
SUBSTANCE: invention relates to a method for extracting lithium. Method for separating lithium includes dissolving lithium phosphate containing impurities in the form of an alkaline earth metal in an aqueous acid solution, introducing an additive, which is a substance capable of simultaneously precipitating phosphate anions and impurities into the resulting solution, to obtain a lithium-containing solution. The resulting solution is basic.
EFFECT: method provides a high degree of lithium extraction.
