Определено, что максимальная степень раскрываемости полигалит-галитовой руды на компоненты при измельчении приходится на фракцию (–0,5 мм). Установлено, что обогащение полигалит-галитовой руды возможно методом обратной флотации с использованием в качестве собирателя алкилморфолинов. Установлено, что высокие показатели обогащения полигалит-галитовой руды (извлечение галита 95,41 %) достигаются при значительных расходах собирателя (1600 г/т).</p></abstract><trans-abstract xml:lang="en"><p>Studies on the flotation enrichment of polyhalite-halite ore have been carried out. It was determined that the maximum degree of disclosure of polyhalite-halite ore to the components during grinding falls on the fraction (–0.5 mm). It was established that the enrichment of polyhalite-halite ore is possible by the method of reverse flotation using alkylmorpholine as a collector. It was established that high levels of enrichment of polyhalite-halite ore (recovery of halite 95.41 %) are achieved at high dosage of the collector (1600 g/t).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>обогащение</kwd><kwd>флотация</kwd><kwd>полигалит</kwd><kwd>галит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>enrichment</kwd><kwd>flotation</kwd><kwd>polyhalite</kwd><kwd>halite</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Баталин, Ю.
