(54) СПОСОБ ПОЛУЧЕНИЯ РАСТВОРА ХЛОРИСТОГО(54) METHOD FOR PREPARING CHLORIDE SOLUTION
КАЛИЯPotassium
1one
Изобретение относитс к способам переработки шенитовых щелоков, образующихс при комплексной переработке полиминеральнык калийных руд.The invention relates to methods for processing Shenitic liquors, which are formed during the complex processing of polymineral potash ores.
Известен способ переработки хлоридносульфатных растворов, включающий их концентрирование, отделение хлористого натри и повторное концентрирование оставшегос раствора до осаждени хлоридно-сульфатных солей 1, .A known method of processing chloride-sulphate solutions, including their concentration, separation of sodium chloride and re-concentration of the remaining solution to precipitate chloride-sulphate salts 1,.
Известен также способ получени раствора хлористого кали , включающий выпаривание раствора, содержащего хлориды и сульфаты натри , кали и магни , с отделением хлористого натри , повторное выпаривание раствора с отделением искусственного какинита и дальнейшее выпаривание с отделением карналлита 2.There is also known a method of obtaining a solution of potassium chloride, which includes evaporation of a solution containing chlorides and sulphates of sodium, potassium and magnesium, with separation of sodium chloride, re-evaporation of the solution with separation of artificial kakita and further evaporation with separation of carnallite 2.
Недостатком этого способа вл етс сложность осуществлени процесса.The disadvantage of this method is the complexity of the process.
Цель изобретени - упрощение процесса за счет сокращени стадий выпарки .The purpose of the invention is to simplify the process by reducing the evaporation stages.
Поставленна цель достигаетс предлагаемым способом, включающш выпаривание раствора, содержащего хлориды и сульфаты натри , кали и магни , и отделений хлористого натри , причемThe goal is achieved by the proposed method, including the evaporation of a solution containing chlorides and sulphates of sodium, potassium and magnesium, and the separation of sodium chloride, and
после отделени хлористого натри раствор обрабатывают 2,7-5,4%-ным раствором гидроокиси кали .after separation of sodium chloride, the solution is treated with a 2.7-5.4% solution of potassium hydroxide.
.Это позвол ет исключить из технологической схемы переработку шенитовых щелоков вторую и третью стадии выпарки, стадии разложени карналлита и растворени хлористого кали . Концентраци примен емой щелочи This makes it possible to exclude from the technological scheme the processing of chenite liquors the second and third stages of evaporation, the stage of decomposition of carnallite and the dissolution of potassium chloride. Alkali Concentration Used
0 обусловлена необходимостью получени 4 8%-ного раствора хлористого кали , пригодного дл дальнейшего использовани на стадии получени сульфата кали .0 due to the need to obtain 4 8% solution of potassium chloride, suitable for further use at the stage of obtaining potassium sulfate.
