“…When enriching lead-zinc sulfide ores, only up to one tenth of the ore passes into a concentrate (Turkebaev and Sadykov, 1988;Shevko et al, 2021a). The rest (most) is stored in dumps, is used to fill the worked-out area (Feigl et al, 2010;Behera et al, 2020;Akkaya et al, 2021) or, at best, is used in the construction industry (for example, as an aggregate in concrete (Evdokimov et al, 2016;Peng et al, 2021;Onukwuli and Nnanwube, 2022;Ibrahim and Atmaca, 2022), the production of silicate and ceramic wall materials (Liu et al, 2019;Zhou et al, 2021;Zou et al, 2022), cement and concrete (Liang et al, 2017;Saedi et al, 2022)). The vast majority of enrichment tailings contains a significant amount of non-ferrous metals.…”

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.

“…It has become a powerful tool for the study of new materials of multi-component glass-ceramics [6][7][8]. With the enhancement of people's awareness of environmental protection, glass-ceramics prepared from solid waste have become a research hotspot of high-value utilization of solid waste [9][10][11][12][13]. As the main components of red mud contain Na 2 O, CaO, Al 2 O 3 , and SiO 2 , commonly used in microcrystal systems, many researchers hope to prepare glass-ceramics from pure red mud.…”

The preparation of glass–ceramics with red mud and steel slag can not only solve the pollution problem caused by industrial waste slag but also produce economic benefits. It is difficult to analyze the high-temperature melt with the existing test methods, so the simulation experiment with molecular dynamics calculation becomes an important research method. The effects of steel slag content on the microstructure of red mud glass–ceramics were studied by molecular dynamics method. The results show that the binding ability of Si-O, Al-O, and Fe-O decreases with the increase in steel slag content. The number of Si-O-Si bridge oxygen increased gradually, while the number of Al-O-Al, Al-O-Fe, and Fe-O-Fe bridge oxygen decreased significantly. The number of tetrahedrons [SiO4] increased, the number of tetrahedrons [FeO4] and [AlO4] decreased, and the total number of three tetrahedrons decreased. The mean square displacement value of Si4+ and O2− increases first and then decreases, resulting in the viscosity of the system decreasing first and then increasing. The molecular dynamics method is used to analyze the structure of red mud–steel slag glass–ceramics on the microscopic scale, which can better understand the role of steel slag and has guiding significance for the experiment of this kind of glass–ceramics.
