Abstract

Описан способ получения KNOиз полигалита. В предпочтительном варианте реализации изобретения, способ включает стадии: (а) контактирования полигалита с HNO; (b) добавления Ca(OH)к раствору с осаждением в виде CaSOпо меньшей мере части сульфата, присутствующего в указанном растворе; (с) осаждения в виде Mg(OH)по меньшей мере части Mg, оставшегося в указанном растворе, путем дальнейшего добавления Ca(OH)к оставшемуся раствору; (d) концентрирования раствора с осаждением в виде сульфатного соединения по меньшей мере части сульфата, оставшегося в растворе; (е) отделения по меньшей мере части NaCl из оставшегося раствора; (f) кристаллизации в виде твердого KNOпо меньшей мере части Kи NO, содержащегося в растворе. Данный способ позволяет осуществить прямое превращение полигалита в KNOс чистотой, превышающей 98,5%, который по существу степени не содержит примесей магния и сульфата.
