Abstract: Magnetic separation is an effective method of processing coal beneficiation waste The problem of processing coal beneficiation waste is a pressing issue for the modern mining industry. Complex processing, which involves the full use of waste, is becoming increasingly popular. At the same time, coal beneficiation waste should be considered as poor ores, since it contains valuable components in small quantities. One of the most effective methods for extracting iron-containing components from coal beneficiation waste is magnetic separation. This method is widely used in the mining industry for the enrichment of various ores, both metallic and non-metallic. In this paper, we study the possibility of using magnetic separation for processing coal beneficiation waste of JSC TsOF "BEREZOVSKAYA" BF-4, BF-5. The tests were carried out using the EVS-15/5 electromagnetic gross separator designed for weakly magnetic ores. The experiments were carried out at different current strengths: 5A, 10A, 15A. As a result of the studies carried out using X-ray fluorescence analysis on the vacuum wave-dispersive X-ray fluorescence spectrometer "SPECTROSCAN MAX-GVM", it was concluded that magnetic separation effectively extracts iron-containing components from coal washing waste. The optimal processing mode includes: Grinding coal washing waste to a size of 0.032 mm. Magnetic separation at a current of 10 A. Research data show that: Magnetic separation allows for the effective extraction of iron-containing components from coal washing waste. The optimal processing mode depends on the specific type of waste. The use of magnetic separation allows for increasing the economic efficiency of coal washing waste processing, as it allows for the extraction of valuable components and the reduction of the amount of waste sent for disposal. Additional advantages of magnetic separation: Environmental friendliness - the method does not require the use of chemical reagents. High efficiency - allows for the extraction of a significant portion of valuable components. Relative simplicity in implementation. Thus, magnetic separation is an effective and environmentally friendly method of processing coal enrichment waste, allowing extracting valuable components and reducing the amount of waste sent to burial.
