“…The typical diffraction reflections are seen, making it possible to determine the phases available. Table 4 represents the crystalline phases' semiquantitative X-ray phase analysis findings [19]. When analyzing Table 3, it was found that the basis of the slag sample is an amorphous substance with the stated crystalline phases with applied reflections.…”

“…The investigation of the sample in the polished briquet in the incident light, exhibited in Figure 1, identified that the slag sample is composed of an amorphous matrix with multiple heterogeneous copper mineral phase inclusions outwardly resembling natural copper sulfide minerals, like native copper and chalcopyrite, that are frequently round and isometric, have typical of chalcopyrite light-yellow color [14,19].…”

The paper deals with analysis and findings of investigation of technogenic plumbum-zinc slag residuals that involve a great deal of poisonous compounds such as cadmium, osmium, plumbum, zinc, hazardous origins of environmental contamination. In connection with the outdoor storing of slags, an excess of the plumbum critical concentration was derived. Technogenic slag residuals' reclamation is crucial for minimizing the detrimental effect on health and safety, improving the region's ecological setting. At that, slags are high-value crude materials involving rare-earth and non-ferrous metal compunds. The paper demonstrates the findings of laboratory tests of slags to specify the quantitative and qualitative composition of highvalue components in the plumbum residuals, the ability of their subsequent treatment and reclamation. The heavy slag fraction material was investigated on JEOL IXA-8230 Electron Probe microanalyzer. The running slag sample's X-ray diffraction analysis was carried out on DRON-4 diffractometer with graphite monochromator, Cu radiation. Heavy fractions were separated from the samples, artifactural polished microsections (briquets) were made. The polished microsections were investigated in index-matching fluids and under LEICA DM 2500P microscope. The findings identified that plumbum slags involve a considerable body of non-ferrous metal compounds, which allow to make the reclamation of poisonous plumbum residuals functional and cost-effective.
