In order to use cheap raw materials in the preparation of petroleum coke and its further use in synthetic iron smelting were used highly viscous oil of "Karazhanbas" crude oil and oil sands of deposits "Munaily Mola" and "Beke". Organic part of oil sand was separated out by extraction method and used its organic part, which contained in an amount of 16% (average content). In addition to purely scientific and technical-economic aspects has the meaning, and solve environmental problems. Kazakhstan has significant reserves of oil, which is contained in the form adsorbed on the mineral component of soil, such as sand and clay. These oil sands were formed millions of years ago and occupy large areas of Kazakhstan. Industrial working off of these deposits with their further reclamation will reduce oil evaporation and return these areas to further use. Under laboratory conditions, the organic part of oil sands extracted by the extraction method, but group of researchers has been tried as well a thermal extraction method and ultrasonic method. It was scheduled testing and other methods of extraction of the organic part from the feedstock. Which of these methods would be economically justified should show further tests on the pilot and semi-industrial installations. Historically, for the production of petroleum coke used in petrochemical processing products, fuel oil and heavy distillates. In the paper, for the first time used natural, previously few used, oil products. High-viscosity oil in Kazakhstan make up a significant portion of its oil reserves and industrial use them is difficult, due to the small content of light petroleum fractions, but at the same time, the fractional composition of the oil is a valuable product for the production of petroleum coke.
