This study investigated the solvent extraction conditions of organic components from bitumen-bearing rocks collected in the Chimyon area of the Fergana Region. Benzene and chloroform were used as extracting solvents. The solvent concentration was varied from 5 to 30%, the solvent-to-rock mass ratio from 1:1 to 1:10, and the extraction temperature from 20 to 90 °C. When benzene was used, the extraction degree increased from 21.9 to 51.4%. Under the same ranges of process parameters, chloroform provided an extraction degree ranging from 41.4 to 73.1%. The results showed that the combined increase in solvent concentration, solvent amount, and temperature promoted the transfer of bituminous components from the mineral matrix into the liquid phase. Chloroform exhibited higher extraction efficiency than benzene, indicating its stronger solvating ability toward the hydrocarbon and resinous components contained in the Chimyon rock samples. The obtained findings provide a scientific basis for developing a processing technology for local bitumen- bearing rocks and recovering their valuable organic components.
