Abstract: In the operation of automobile engines mineral and synthetic oils waste is produced and accumulated in huge quantities. Its recycling and re-using in the production is an important and urgent task today, in terms of economy and ecology. In this study, we investigated the effects of ozonation on the composition of the used synthetic and mineral motor oils (WМO) with the aim of modifying their chemical composition and use as flotation agents for the enrichment of coal. As objects of research we selected used synthetic motor oil (WSO) and mineral oil which had been used in cars (WOC) and trucks (WOT). For chemical modification, the method of ozone treatment was used which had proven its worth in the petrochemical industry. It has been demonstrated that pre-ozonation contributes to an increase in light boiling components share in the composition of the studied oils, it allows reducing waste viscosity and improves their flotation properties in the coking coal benefication. Using ozonated used oils in the flotation of coal significantly increases the concentrate yield, reduces ash content, increases the mineralization of flotation tailings, and as a consequence increases the selectivity coefficient of the process. The maximum positive effect of ozonation is observed in the samples of mineral oils.
