Abstract. The article considers the effect of ammonia on the extracted phosphoric acid obtained by the clinker method from the washed and dried phosphorite concentrate (YQFK) formed by the thermal enrichment of the Central Kyzylkum (MQ) phosphorite. The X-ray analysis, absorption, and scattering of the obtained ammophos were determined. The main composition of the obtained ammophos was determined to be as follows: P2O5total., P2O5o'zl. by citric acid (LK), P2O5o'zl. by trilon-B (trB.) and water-soluble (aqueous) P2O5aqueous. The values were determined to be 47.85; 47.39; 47.30 and 43.28%, respectively, the nitrogen content was 12.32%. 546.08 kg of ammophos were produced from 1000 kg of 27.4% EFK
