“…7,9 It should be noted that the crystals mainly fall in the form of drusy aggregates.It is believed that druses are formed either with very slow crystallization, or with very slow mixing, or with constrained crystal growth when they come into contact with the bottom or walls of the apparatus, the faces of several growing crystals, the presence of impurities in the solution, etc. 10 The formation and appearance of drusus crystals are mainly determined by the shape of the crystal nuclei, the surface on which they grow, and the interaction of several growing crystals. In our studies, we assume that the formation of drusas is affected by the process of slow mixing and the presence of impurities in the acid.…”

One of the important sources of raw materials for the production of mineral fertilizers in wet-process phosphoric acid (WPA). It is known that WPA is obtained by treating natural raw materials directly with sulfuric acid. Since WPA is used in the production of mineral fertilizers, it is necessary to solve environmental problems with the rational and comprehensive use of mineral raw materials. This is because, during the extraction of natural raw materials, all impurities contained in phosphate raw materials are transferred to the composition of WPA. Therefore, the main goal is to clean the WPA from impurities. This article discusses the purification of WPA from the fluoride deposition method with the use of inorganic reagents. As the inorganic reagent for defluorination WPA used sodium salt. The influence of temperature, time and norm of sodium salt on the deposition method is studied. As a result, the optimal parameters of the purification of WPA by precipitation were determined: the norm of sodium salt -140% of stoichiometry; temperature -40-50 0 C; time -30 min. Under these conditions, the degree of purification of WPA from fluorine is 84%. The size of the crystals formed during the deposition of sodium silicofluoride is 40-50 microns. Composition of the purified WPA under these conditions (wt. %): P2O5 -19; F -0.24.

“…DAP, obtained using phosphoric acid with a lower concentration than traditional technology, has lower physical and mechanical properties, increased hygroscopicity and traceability [10]. To preserve the quality of DAF during transportation and storage the moisture content of the finished product shall be not more than 2.0 %; for this purpose-exposure of the product to produce at least 2 hours and the temperature of the shipment is maintained in accordance with the requirements of normative technical documentation.…”

“…To increase the environmental safety of not only fertilizers, but also products of various crops, it is recommended to include in the compound fertilizer glauconite, which has the ability to absorb 66 to 99% or more of aqueous solutions of heavy metals and radionuclides. This allows not only to increase iron, zinc, sulfur, magnesium, calcium and other nutrients, but also to obtain multicomponent fertilizers containing other trace elements that fertilize saline soil resources [4,5].…”
