Изобретение относитс к способам получени бесхлорных калийных удобрений из полиминеральных руд, например, Прикарпатского месторождени .The invention relates to methods for producing chlorine-free potash fertilizers from polymineral ores, for example, the Carpathian deposit.
Известен способ получени сульфатных калийных солей путем растворени лангбейнитового флотоконцентрата, полученного при переработке полиминеральных руд с последующей переработкой образовавшегос эпсомитового щелока.A method is known for producing sulphate potassium salts by dissolving a langbeinite flotation concentrate obtained by processing polymineral ores followed by processing the formed epsomitic liquor.
Однако при таком способе наблюдаетс пенообразование при выпарке щелока из-за наличи флотационных реагентов (синтетических жирных кислот). Кроме того, вторична флотаци калийных солей при кристаллизации и сгущении приводит к их потер м.However, with this method, foaming is observed when the liquor is evaporated due to the presence of flotation agents (synthetic fatty acids). In addition, the secondary flotation of potassium salts during crystallization and condensation leads to their loss of m.
Предлагаемый способ отличаетс тем, что зпсомитовый щелок подкисл ют до рН 5,8- 6,2 и подвергают упариванию на 30-32%.The proposed method is characterized in that the zpsomite liquor is acidified to a pH of 5.8-6.2 and is subjected to evaporation by 30-32%.
Это позвол ет упростить процесс, так как устран етс пенообразование, а также повысить степень извлечени кали .This simplifies the process, as foaming is eliminated, and also increases the degree of potassium recovery.
Пример. В раствор солей, соответствующих по составу лангбейнитовому маточнику, получаемому при растворении лангбейнитополигалитового концентрата (рН 6,85), добавл ют различные жирные кислоты: валериановую (Cs), каприловую (Cs) и каприновуюExample. In the solution of salts corresponding in composition to the langbeinite mother liquor obtained by dissolving the langbein polypolyte concentrate (pH 6.85), various fatty acids are added: valeric (Cs), caprylic (Cs) and capric
(Сю), - вход щие в состав примен емой дл флотации фракции кислот .(Xu), - fractions of acids that are part of the flotation used for flotation.
Исходные концентрации кислот составл ют 55 мг на 200 мл маточника.The initial acid concentrations are 55 mg per 200 ml of liquor.
При упаривании такой смеси па 15% (дл предотвращени высаливани добавл ют 100 мл воды) концентраци кислот Cs, Cs и Сю в растворе уменьшаетс на 60, 70 и 80% соответственно.When this mixture is evaporated by 15% (100 ml of water is added to prevent salting out), the concentration of Cs, Cs and Xu acids in the solution decreases by 60, 70 and 80%, respectively.
Подкисление солевого раствора до рН 6,0 способствует более полному удалению кислот по сравнению с предыдущими результатами. Так, каприлова кислота при рН 6,0 при упаривании раствора на 15% отгон етс на 90%,Acidification of the salt solution to a pH of 6.0 contributes to a more complete removal of acids compared with previous results. Thus, caprylic acid at pH 6.0, by evaporation of the solution, is distilled off by 15% by 90%,
а не на 80% как при рН 6,85.rather than 80% like at pH 6.85.
