| abstract | FIELD: agriculture. n SUBSTANCE: method substance consists in decomposition of apatite concentrate with nitric acid, extraction of some calcium nitrate from nitrate-phosphate extract by means of crystallisation, mixing of phosphorous-containing semi-finished product with previously treated low-grade phosphor raw materials and processing of mixture into a complex fertiliser. Preliminary treatment of low-grade phosphate raw material is executed with nitric acid with further separation of insoluble residue, and liquid products of preliminary treatment are mixed with nitrate-phosphate extract after calcium nitrate portion has been extracted from it. Low-grade phosphate raw materials applied are represented by crushed phosphorite containing 24.6 wt % of P 2 O 5 (Karatau phosphorite). Ratio of apatite concentrate and low-grade phosphate raw materials in terms of P 2 O 5 is maintained within the limits of (2 รท 7) : 1. n EFFECT: method makes it possible to improve strength of produced fertiliser granules. n 3 cl, 1 tbl, 4 ex |
