tailings solution

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

In this article yields and sequence of crystallization of salts during cooling degreeal partially evaporated solution Каlush tailings were studied. Installed cooling temperature regimes which will provide obtaining sodium chloride, potassium-magnesium fertilizer, epsomite etc. Досліджено виходи і послідовність кристалізації солей під час ступеневого охолодження частково випаруваних розчинів Калуського хвостосховища. Визначено температурні режими охолодження, які забезпечать одержання натрію хлориду, калійно-магнієвого добрива, епсоміту тощо.

In this paper the experimental results of extraction magnesium chloride from solid intermediate product of processing of solution Stebnik's tailings with using 87.4...89.5 % aqueous solutions of isopropyl alcohol in the mass ratio between the solid and liquid phases 1:2.0...5.0 and the distillation of isopropyl alcohol with obtained solutions are presented. It is shown that the necessary conditions for obtaining of conditioned bischofite are the content in extractant 89.5 wt. % of isopropyl alcohol and the weight ratio between the solid and liquid phases that is equal 1:3,0...1:3.5.
