USE OF COMPOSITE REAGENTS FOR THE SEPARATION OF NON-FERROUS METALS FROM COALS BY THE FLOTATION METHOD
First of all, this research paper presents brief information on the preparation of SFKM-1 and SFKM-2 surfactants based on local
raw materials. Information is provided on the optimal ratio of SFKM-2 branded composition, which contains SFKM-1 flotation
reagent with sulfanol. When analyzing the physical and chemical properties of Angren lignite of 2BR-B2 and 2BOMSSh-B2
brands, the optimal volume was determined. The surfactant used in coal beneficiation was selected and its efficiency was studied.
The positive results of gravity and flotation enrichment of coal using Oxalya T-66 foaming reagent are presented. The
quantitative and qualitative composition of the groups of the obtained SFKM-2 composite material was studied using IR-
spectroscopy analysis. Information about the analysis of the received IR spectrum is presented.
