Abstract

Предложен способ получения KNOиз полигалита. Способ включает стадии разложения указанного полигалита на сингенит, гипс и растворимые компоненты, обработки твердых продуктов разложения последовательно HNOи основным соединением Ca, осаждения образованного таким образом CaSOи кристаллизации KNOиз оставшегося раствора. Способ позволяет извлекать до 75% калия, присутствующего в неочищенном полигалите, в виде KNOи, по существу, весь остаток в виде калиймагниевой сульфатной соли.
