The flotation activity of collectors of different chemical composition and structure during the flotation of coal with differ-ent mineralization of organic matter carried out. High efficiency of the flotation process, used as a reagent-collector of a technical product of oil refining "Nefras -150/330" is installed. The high flotation activity of the reagent Nefras-150/330 is due to the presence in the group chemical composition of the reagent in the predominant amount of aromatic hydrocarbons. The use of "Nefras-150/3302" allows to increase the extraction of combustible mass in the concentrate by 3.1-7.6% compared with the use of other col-lector reagents. It has been established that the use of the reagent - collector "Nefras-150/330" allows to increase the ash content of flotation waste by 5.4-9.0%, depending on the mineralization of the organic mass of coal supplied to enrichment.
