In this study, new f lotation reagents were developed for the coal beneficiation process, and their effectiveness was evaluated using experimental methods. The main objective of the research is to improve the efficiency of the beneficiation process by enhancing the physical and chemical properties of coal. For this purpose, various spectroscopic and chemical analysis methods, including X-ray f luorescence (XRF), X-ray diffraction (XRD), and infrared (IR) spectral analysis techniques, were employed. The results demonstrated that the use of the newly developed SFKM-2 composite f lotation reagent increases the calorific value of coal while also reducing the environmental impact of coal residues. The study’s findings propose new approaches to enhancing the efficiency of f lotation reagents and open up possibilities for industrial-scale applications. The technological scheme of coal enrichment by f lotation method is described. In order to develop a waste-free technology, a chemical analysis of the waste produced as a result of the enrichment was carried out. Acidic oxides are formed as a result of combustion of sulfur in coal. The use of silicon compounds with a crystalline structure is one of the requirements for silicon compounds used in the glass industry. Coals passed through the drum are processed in a f lotation reactor and sent to a coal dryer. Enriched and dried coals are sent to a briquetting machine and a finished product in the form of briquettes is obtained. In addition, the developed SFKM-2 composite material IK-spectrum image and image data are presented. The ash content was analyzed by the X-ray f luorescence method and the results were presented and scientifically analyzed. Additives were added to the f lotation device, new f lotation reagents and collectors were used.
