An extraction method of oil-bituminous rocks organic component from the mineral one by ultrasonic treatment method of oil-bituminous rocks, as well as oil and oil products from contaminated soil using available solvents in the presence of surfactants based on a gossypol resin and polyelectrolytes – hydrolyzed polyacrylonitrile derivatives (Uniflok) has been developed. At that, it has been established that the organic component extraction rate depends not only on the ultrasonic treatment, but also on the used solvents (when using benzol, diesel fuel, kerosene, the yield composes 10-12 ml during 25-32 minutes, when using white spirit and kerosene, the yield increases in 2 times up to 18 ml during 10-15 minutes) and concentration of added flocculent (at the concentration of 0,1% the organic component yield attains up to 18 ml and the settling time decreases from 39-40 m³·10^-3 to 9 m³·10^-3 Results of IR-spectroscopic and electronic-microscopic studies of mineralogical composition and microstructure of oil-bituminous rocks organic and mineral components’ samples show that compacting of the structure and Uniflok flocculent flocculating property, probably, occurs at the expense of adsorbed macromolecules, participating in creation of “bridging” links between particles of oil-bituminous rocks organic and inorganic components’ disperse phase.
