“…The main disadvantage of tannins' application as depressants is considered to be their non-selectivity. However, it was shown that, depending on the flotation conditions, concentration, and alkalinity of the medium, oxygen-containing organic hydrophilic colloids can have different modifying effects on the floatability of sulfide minerals, which allows us to consider them as promising reagents for the selective sulfide flotation [67].…”

An urgent technological, economic and environmental task of mining and metallurgical enterprises is to involve poor, off-balance and hard-to-beneficiate ores in the technological process, as well as accumulated and current waste from mining and metallurgical industries. As the reserves of developed deposits are depleted, technogenic objects may become a priority, and in some cases the only, source of mineral raw materials. Mining wastes represent a large reserve of raw materials for the extraction of non-ferrous and precious metals, and at the same time, they are centers of local or regional environmental pollution. Stale waste re-processing may promote territorial cultivation and reduce the environmental burden. The conventional methods of poor ore and waste treatment do not fully provide for a sufficient separation degree of high metal extraction, and lead to significant valuable ore losses, while the quality of the obtained concentrates often does not meet the requirements for subsequent technological process. In this regard, the development of novel chelating agents with specific functional groups that can selectively adsorb on the mineral surface, change the contrast of chemical surface composition and improve the flotation properties of mineral complexes, is an innovative solution for increasing their flotation selectivity. Furthermore, the synthesis and application of novel flotation reagents may help to replace toxic reagents by ecologically friendly or less-toxic ones.

“…For instance, for high gold pyrite (more than 9 g/t), it is efficient to use its selective extraction first and then the gravitational flotation scheme [7]. The flotation separation of pyrite involves organic complexing agents [8].…”

Interpreted data of the phase analysis of the Far East ore bodies made it possible to characterize rebellious behavior of ores under study. The researchers propose an integrated flow sheet composed of gravitational preparation, flotation and metallurgical processing flow sheets for beneficiation of rebellious auric-arsenical ore, and present the beneficiation parameters for ores of moderate sorption capacity.
