ARTICLE ANNOTATION

The question of the organisation of NPK fertilizers manufacture with the maintenance not less than 40 % of nutritious elements from phosphorites Central Kizikum is considered. In the developed flow sheet use of enriched and washed dried phosphorite containing 17-26 % P2O5 is provided. At low maintenance P2O5 in phosphorite raw materials it preliminary is exposed to acid enrichment. It was shown the possibility that nitrogen-phosphate-potassium fertilizers and nitro – ammophos - potassium can be prepared based on nitric and sulfuric acid processing low-grade phosphorite from Central Kyzyl Kum. The rough calculation of the consumption coefficients of obtaining nitro – ammophos - potassium and nitro-phosphate - potassium (mono- and dicalcium nitro-phosphate - potassium) at various CaO / P2O5 ratios in washed dried phosphorite with a content of 26% P2O5 was carried out. The triple fertilizers at least 40% nutrient elements are suitable for application in agriculture where their efficiency will have great significance in term of yield. The advantages of the developed scheme are the possibility of obtaining a concentrated NPK-fertilizer with balanced nutrients in it, flexibility, allowing to obtain various technical salts of phosphorus, low energy consumption, as well as the possibility of using any phosphate raw material.
