Установлено, что совместное введение как амилового спирта, так и гликолевого эфира с алкилморфолином в процесс флотации хлорида натрия позволяет достичь высоких технологических показателей и снизить расход дорогостоящего алкилморфолина в 2 раза. Установлено, что применение соснового масла в качестве пенообразователя в смеси с алкилморфолином позволяет снизить расход собирателя в 2,2 раза.</p></abstract><trans-abstract xml:lang="en"><p>The effect of foaming agents of different chemical nature (amyl alcohol, glycolic ether, pine oil) on the flotation of halite from polyhalite ores using alkylmorpholine as a collector was investigated. It was established that the combined adding of amyl alcohol with alkylmorpholine and glycolic ether with alkylmorpholine in the process of sodium chloride flotation allows achieving high technological performance and reduces the consumption of expensive alkylmorpholine by 2 times. The use of pine oil as a foaming agent in a mixture with alkylmorpholine has been established to reduce the collector consumption by 2.2 times.</p><p> </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">Позняк, Н.
