The authors work out a new approach to the selection of reagents for the flotation recovery of cations of nonferrous metals on the basis of calculation of their quantum-chemical characteristics and the Pearson's principle. The possibility to use as a criterion for assessing the flotation activity of organic compounds the values of their absolute rigidity is proved. They propose and test a new class of efficient collector reagents to extract the ions of nonferrous metals.
Разработан новый подход к подбору реагентов для флотационного извлечения катионов цветных металлов на основе расчета их квантово-химических характеристик и принципа Пирсона. Обоснована возможность использования в качестве критерия оценки флотационной активности органических соединений значения их абсолютной жесткости. Предложен и апробирован новый класс эффективных реагентов-собирателей для извлечения ионов цветных металлов.
