Technological aspects of a new method of obtaining magnesium phosphate based on the interaction of magnesium chloride from liquid waste from the processing of potassium ores and sodium phosphate have been studied. The influence of precipitation conditions of magnesium phosphate crystal hydrate, washing of the obtained precipitate and its drying on the yield and product quality was studied. Rational technological parameters of realization of the main stages are chosen. The developed technological process, in comparison with the known ones, allows to simplify the technology, reduce the cost of production, balance the composition of liquid waste for further processing into potassium-magnesium fertilizers.

“…There is a known method according to which the natural kainite purified from sodium chloride under industrial conditions is converted into schoenite in the schoenite solution at ambient temperature [3]. Schoenite crystallization is also used for the conversion of langbeinite and kieserite with potassium chloride and natural mirabilite into schoenite [4].…”

Abstract.1 The conversion of kainite and solution saturated after ore dissolving into schoenite has been studied under laboratory conditions within 293-333 К for 1 h. The highest conversion was found to be at 333 К for 1 h. Using Arrhenius equation the "apparent" activation energy was calculated. Its value shows the transition area of the conversion. The cooling and conversion were studied under various values of air mixing intensity. The air consumption was determined to achieve the highest conversion. Kainite conversion into schoenite in the saturated solution at approximately 333 К is followed by cooling via air bubbling. This approach allows to produce schoenite by a simple way without special expensive equipment.
