Сравнительные исследования флотации с использованием соснового масла и ПЭГ-400 показали эффективность применения данных реагентов в комбинации. С использованием коллоидно-химических методов установлено влияние добавок вспенивателей на мицеллярную структуру растворов амина и адсорбцию амина на поверхности хлорида калия. Лабораторные исследования показали, что введение комбинации соснового масла и ПЭГ-400 позволяет извлечь 90,3 % хлорида калия в концентрат при содержании 87,0 % KCl. Показатели извлечения при использовании комбинации пенообразователей выше, чем при введении в собирательную смесь одного из вспенивателей. Таким образом удалось достичь наилучших результатов при использовании комбинации пенообразователей. Оптимальный расход в лабораторных условиях и соснового масла и ПЭГ-400 – 10 г/т руды.</p></abstract><trans-abstract xml:lang="en"><p>A research on the process of enrichment of potash ore using a collective mixture based on higher aliphatic amines, pine oil, and polyethylene glycol (PEG-400) has been carried out. Comparative flotation studies using pine oil and PEG-400 have shown the effectiveness of combined use of these reagents. The effect of adding foaming agents on the micellar structure of amine solutions and the adsorption of amine on the surface of potassium chloride was proved by colloidalchemical methods. It was shown that the introduction of a combination of pine oil and PEG-400 makes it possible to extract 90.3% of potassium chloride into a concentrate at content 87.0 % of potassium chloride. Recovery rates when using a combination of foaming agents are higher than those for adding only one of the foaming agents to the collective mixture. Thus, the best performance was achieved by using a combination of foaming agents. The optimal consumption in laboratory conditions for pine oil and PEG-400 was 10 g/t of ore.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>флотационное обогащение</kwd><kwd>калийная руда</kwd><kwd>катионные поверхностно-активные вещества</kwd><kwd>собиратель</kwd><kwd>пенообразователь</kwd><kwd>извлечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flotation enrichment</kwd><kwd>potash ore</kwd><kwd>cationic surfactants</kwd><kwd>collector</kwd><kwd>hydrofobizator</kwd><kwd>foaming agent</kwd><kwd>recovery</kwd><kwd>surface tension</kwd><kwd>adsorption</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">Laskowski, J.
