“…The vast majority of enrichment tailings contains a significant amount of non-ferrous metals. As a rule, the processing of such tailings is reduced to the base metal flotation (Snurrnikov, 1986;Pacholewska et al, 2007;Semushkina et al, 2017;Feng et al, 2019;Hussaini et al, 2021). For example, during the flotation of tailings containing zinc, it is possible to obtain a standard pyrite and barite concentrate, sulfide middlings containing 6.2-7.7% Zn, 0.9-1.1% Pb and 0.7-0.9 % Cu.…”

“…The extraction of non-ferrous metals from the ore in this case increases by 4.5% (Snurrnikov, 1986). And, with the combined use of a combined collector and a water-air microemulsion generator, the extraction of zinc increases by 14.13% (Semushkina et al, 2017). The work (Bekturganov et al, 2017) shows that using a flotation agent from a mixture of modified dithiophosphate, TC-1000 thionocarbamate and modified xanthate during tailings flotation allows increasing the degree of zinc extraction from the ore to 8.64%.…”

The article presents the results of thermodynamic and experimental research on the processing of cinders from the firing of Shalkiya deposit lead-zinc ore tailings with the production of siliceous ferroalloys. Thermodynamic modeling carried out using the HSC-6.0 complex based on the Gibbs energy minimization principle showed that the interaction occur with the formation of CaSiO3, FeSiO3, MgSiO3, K2OˑSiO2, FeSi, Fe5Si3, SiC, Fe3Si, Si, SiOg, FeSi2.33, FeSi2, CaSi, Zn, Zng, Pb, Pbg; an increase in the iron amount in the system allows increasing the silicon extraction degree into the alloy at 1800°C to 76%, to reduce the silicon concentration in the alloy from 41 to 24%; FS25 grade ferrosilicon formed at 1752-1867°C in the presence of 88-100% iron, and FS45 grade ferrosilicon – at 1863-1900°C and 20-22.4% iron. Electric melting of a charge containing 63.83% calcined cinder of tailings, 19.15% coke, and 17.02% steel chips allows to obtain FS45 grade ferrosilicon (44.1-43.9% Si) with the extraction of 69.7% silicon and sublimates with the content of 32-38% zinc and lead. The results obtained allow complex processing of lead-zinc sulfide ore tailings with the extraction of not only non-ferrous metals, but also silicon in the ferroalloy.

The monograph presents modern research directions in the field of processing of refractory gold-bearing ores and technogenic raw materials, the results of studying the physicochemical properties of the mineral complexes of the ore of the Akbakai deposit, the effect of a new flotation modifier - butylpolyethylenepolyamine - on the fixation of butyl xanthate on the surface of sulfide minerals. The effectiveness of the use of butyl polyethylene-polyamine in the enrichment of refractory gold-bearing ore and ultrafine grinding of the flotation concentrate during its cyanidation is shown. The results of studies on the concentration of stale tailings of gold recovery plants are presented. The monograph may be of interest to researchers and specialists working in the field of enrichment of gold-bearing mineral and technogenic raw materials.

“…It was found in [4][5][6][7] that in order to improve the quality of extraction of metals into concentrate, in addition to achieving the required dimension, other approaches can be considered in detail, so in the work on a sample of stale sulfide copper-nickel off-balance ores and tailings, an assessment was made of the effect of grinding size on flotation performance, at different pH values (in alkaline and acidic environments) on the tailings. The extraction of nickel and copper into the total foam product in this case was 2.5 and 2.7% higher, respectively, than in an acidic medium.…”

The task of the tests was to study the material composition in order to develop a rational technology for the enrichment of porphyry copper balance and off-balance ores of the Yoshlik I and Kalmakyr deposits to obtain collective, copper- and molybdenum-containing concentrates, finished products in the form of copper, molybdenum and pyrite concentrates. The material composition of ore samples was studied using spectral, chemical, assay, granulometric, phase, rational for gold and silver, mineralogical, and other types of analyses. Due to the absence of significant bonds of gold with pyrite, there is no expediency to carry out extensive studies of the hydrometallurgical processing of pyrite concentrates. It is possible to set up a basic experiment to determine the proportion of cyanidated gold. When processing ore raw materials enriched by flotation, not only various flotation reagents-collectors, technological parameters, but also the grinding size and material composition of the ore are important for obtaining a concentrate, since grinding the ore to the required size is about half the cost of obtaining a concentrate.
