Abstract: | It is considered how the organic reagents, complexing agents, change floatability of the varieties of pyrite with different
content of goal. The authors continue studying the flotation effect of the reagent PROX capable to selectively decrease floatability
of some pyrite varieties in the presence of xanthogenate due to formation of a hydrophilic complex compound with ferric iron
at the phase interface of the mineral surface — liquid, and to reduce sorption of xanthogenate. A phytogenous reagent is suggested
as an alternative to the multi-component PROX. The new reagent mechanism is described by examining the chromatographic behavior
of the compound of this reagent and ferric iron salt.
