“…The possibility of their use for the recovery of non-ferrous metals was shown earlier in the flotation of copper-nickel ore [113]. The HA reagent was tested in the flotation of samples of the stored copper-nickel ore concentration waste in combination with xanthate at a ratio of 1:1 [113]. The results are close to the results of tests using xanthate and aeroflot, and the recovery of nickel into the froth in this case was 48.91%, which is 2.07% higher than when using a composition of sulfhydryl collectors (Table 8).…”

The processing of previously unclaimed ores and wastes as sources of non-ferrous metals, with an associated reduction in the environmental burden, is a promising field of research. Besides, many relatively minor non-ferrous metal deposits with complex mining engineering and geological properties exist, whose development by conventional mining methods is not economically feasible. The theoretical possibility of processing the cut-off grade copper-nickel objects of Murmansk Region was shown. Process conditionswere found making the process economically feasible. Processing these mineral feed types will also allow in the long term to improve the environmental situation in the region.

The search for effective reagents for the flotation of non-ferrous metals from mineral raw materials is an actual problem. The article discusses the results of research on improving the technology of processing copper–molybdenum ores using a combined collector emulsion. The object of research was copper–molybdenum ore containing 0.43% copper and 0.0089% molybdenum. Copper minerals are represented by chalcopyrite 1.2% and chalcocite 0.015%, while covellite is present in a much smaller amount. The main mineral of molybdenum is molybdenite. The cycle of collective copper–molybdenum flotation includes the main flotation, control flotation, and three re-cleanings of concentrate. In the basic mode, the collective Cu–Mo concentrate was produced with the copper content of 16.25% with an extraction of 77.79% and with the molybdenum content of 0.45% with an extraction of 79.38%. Reaflot, thionocarbamate, and butyl xanthate were used in a ratio of 1:3:15 to prepare a combined collector agent. In order to produce the combined collector emulsion, the best degree of dispersion, which amounted to 99.5% of particles with a size of −3.6 μm, was chosen. During the Cu–Mo ore flotation using an optimally dispersed microemulsion of the combined collector agent, a collective Cu–Mo concentrate was obtained with a copper content of 18.2% with an extraction of 83.58%, and with a molybdenum content of 0.49% with an extraction of 88.46%. The use of a combined collector agent increases the extraction of copper into the collective Cu–Mo concentrate by 5.79%, while the extraction of molybdenum increases by 9.08%.

“…The creation of new types of low-toxicity chelating reagents is aimed at increasing the contrast between the valuable minerals and waste rock flotation and, as a result, improving their separation, thus obtaining high-quality concentrates and reducing the loss of valuable metals with waste products [1][2][3][4][5][6].…”

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.
