Improvement of methods for obtaining phosphorus fertilizers by mechanical activation

Abstract

The article deals with the process of mechanical activation and determination of the influence of activating additives on the degree of solubility of low-grade phosphoresces of the Central Kyzylkum. As well as mechanical activation of samples of various types of low-grade phosphoresces with the addition of acid salts NH4H2PO4, (NH4)2HPO4, at a ratio of 5:5 in a mortar mill RM 200, with a mode of increasing the activation time to 60 minutes, by heating the resulting mixture to 200°C in various component ratios. Development of a waste-free and environmentally friendly technology for the production of NPK fertilizers.
