Флотация руд является основным и определяющим технологическим процессом обогащения руд и производства цветных металлов. Процесс флотации требует использования множества химических реагентов, включая собиратели, пенообразователи, модификаторы поверхности, регуляторы рН. Разработка и выбор подходящих реагентов для обрабатываемого материала играют жизненно важную роль для эффективной флотации. Флотационная активность собирателей принципиальным образом зависит от состава и строения гидрофобного и гидрофильного фрагментов, образующих молекулу флотореагента, а также от природы руды, которая подвергается флотационной переработке. В связи с этим выявление и изучение зависимости «структура вещества – флотационная активность», а также поиск новых эффективных флотореагентов являются актуальными задачами прикладной органической и элементоорганической химии и связанных с ними смежных отраслей науки и технологии. В настоящем обзоре представлены синтезы эффективных реагентов-собирателей, а именно ксантогенатов и дитиокарбаматов, на основе литературных данных за последние 5 лет. При необходимости указаны более ранние литературные источники. На схемах приведены условия реакции и выходы целевых соединений. Кроме того, представлены результаты флотационных испытаний на поверхностях различных руд и данные о механизме извлечения концентрата. Представленные в обзоре работы показывают, что закрепление реагентов-собирателей на поверхности минералов можно рассматривать как процесс комплексообразования между функциональными группами собирателя и ионами металлов, находящимися на поверхности минерала.

Ore flotation is the main and defining technological process in ore benefication and non-ferrous metals production. The flotation process requires the use of a variety of chemical reagents, including collectors, frothers, surface modifiers, and pH regulators. The development and selection of suitable reagents for the processed material play a vital role in efficient flotation. The flotation activity of collectors depends fundamentally on the composition and structure of the hydrophobic and hydrophilic fragments forming the flotation agent molecule, as well as on the nature of the ore that undergoes flotation processing. In this regard, the identification and study of the “substance structure–flotation activity” relation, as well as the search for new effective flotation reagents gain importance within applied organic and organoelement chemistry and related branches of science and technology. In this article, we review syntheses of effective collector reagents, namely xanthates and dithiocarbamates, based on the literature data for the past five years. Where necessary, earlier sources are provided. The reaction conditions and yields of the target compounds are presented using schemes. In addition, we present the results of flotation tests on the surfaces of various ores and the data on the mechanism of concentrate extraction. According to the reviewed publications, the fixation of collector reagents on the surface of minerals can be regarded as a complexation process of the collector functional groups and metal ions located on the surface of the mineral.
