A method of extracting the total of lanthanides from extraction phosphoric acid (hereinafter EPA), providing 95-100% extraction of the total of lanthanides into concentrates containing the total of lanthanides from 38.4 to 72.9% and a low content of impurities, characterized in that for for the extraction of the total of lanthanides from EPA and the minimum absorption of impurities, strongly acidic macroporous cation exchangers are used as sorbents. 2. The method according to claim 1, characterized in that the concentration of EPA is in the range from 30 to 38.5 wt.%, And its temperature is from 15 to 80 ° C, preferably from 40 to 80 ° C. The method according to claim 1, characterized in that, in order to increase the purity and quality of the concentrate and ensure the concentration of the amount of REE in it up to 72.9%, the commercial regenerate is subjected to additional extraction purification with 100% tributyl phosphate. The method according to claims 1 and 3, characterized in that, in order to ensure the extraction purification of the commercial regenerate with tributyl phosphate and for the complete desorption of the amount of REE as a stripping solution, an ammonium nitrate solution with a concentration of 200 to 600 g / l, preferably 450-550 g / l 5. The method according to claim 1, characterized in that it is ensured that not only lanthanum, cerium, praseodymium, neodymium, samarium, dysprosium and yttrium, but also such rare individual rare earth elements as europium, gadolinium and holmium are extracted into the commercial regenerate and then into concentrates. 6. The method according to claim 1, characterized in that, in order to ensure 95-100% recovery of the amount of REE from EPA, the complete saturation of strongly acidic macroporous cation exchangers in the amount of REE is carried out in a countercurrent EPA-resin with a volumetric ratio of W: T equal to 8-10: 1, and the complete desorption of the total REE from the cation exchangers is also carried out against
