DETERMINATION OF EQUILIBRIUM PARAMETERS OF EXTRACTION OF IODINE BY MIXTURES OF EXTRACENTS OF VARIOUS NATURE [№ 9 ' 2017]
Complex processing of poor mineral and hydromineral raw materials is a rather urgent task for today due to various reasons. The use of new sources of valuable components can be associated with the depletion of existing deposits, with the inability to process traditional raw materials due to geopolitical, economic, logistical or other reasons. Due to the fact that iodine does not form any significant deposits in the earth’s crust in the form of minerals, since it is a very mobile migrant, but tends to accumulate in groundwater near oil and gas condensate deposits, the use of the latter for iodine mining can be promising. Extraction extraction of iodine from reservoir and drilling waters of natural and technogenic origin is quite effective and economically advantageous. To study the extraction process, model aqueous solutions were used, which in composition are as close as possible to the composition of natural waters. The main equilibrium parameters of the extraction process were determined depending on the composition of the extraction composition. Mixtures of extractants of the aliphatic series — isooctane and cyclohexane and aromatic series — benzene and toluene were investigated. The mineralization of solutions was set by adding sodium chloride in the concentration range from 0 to 4 mol/l. The iodine content corresponded to the minimum industrial concentrations. The method of “isomolar series” and the method of “variable volumes” were used as the basic methods of investigation. In the course of the study, it was determined that, with an optimal ratio of organic and aqueous phases of 1 to 10, the greatest synergistic effect is achieved when using a mixture of extractants of aliphatic and aromatic series in a ratio of 7 to 3. The use of mixtures of this composition allows to achieve the greatest distribution coefficient and extraction ratio.

ODEL OF THE MUTUALLY BENEFICIAL COOPERATION OF THE PASSENGER REGIONAL CARRIERS [№ 9 ' 2015]
Currently the strategic development of the suburban passenger traffic is directed to the formation of the intermodal transport involving rail transport. In the context of legal fragmentation of the transport complex integration of transportation companies through coordination of their activities is impossible without building mutually beneficial relations of participants of the transportation process. The investigation of the existing scientific works on improvement of the suburban complex allowed us to determine that not enough attention given to the formation conditions of mutual cooperation of participants of the transportation process: the model of coordination of the interests of the passenger carriers was not created, both among themselves and with the Executive authorities of subjects of the Russian Federation. Therefore the purpose of this article is to develop a model of mutually beneficial cooperation of passenger carriers. Interaction in this paper is formalized as a graph model, defined in the plane of the formation of the conflict the carriers, proposed to use logistic approach to resolve the conflict between carriers and build optimal route network. As a result of the work carriers on the proposed cooperation schemes is achieved by the additional system effect. This effect is ensures the integrity of the system. It is expressed by the difference between the obtained effect of concerted action of carriers and the amount of economic effects of individual elements of the system. Additional system effect is possible only in terms of removing contradictions in the system. The amount of Agency fee can be set from the condition of maximizing the profitability of carriers. Proposed in the present work, the model makes it possible to form regional route network from the point of view of realization of interests of subjects of the transportation process.

GEOCHEMICAL FEATURES OF DISTRIBUTION OF PRECIOUS METALS IN THE OIL-GAS FIELDS OF THE ORENBURG REGION [№ 7 ' 2015]
Non-ferrous and precious metals in the hydrocarbon feedstock are of interest in connection with the work on the study of noble metallogeny carbonaceous formations Ural metallogenic provinces and are important in platinoids metallogenic zoning specialization eponymous folded region of East Orenburg. The purpose of this study was to establish the geochemical characteristics of the distribution of Pt, Pd, Au and Ag in oil and gas fields in western Orenburg. To solve this problem was in the creation of maps izokontsentrat metals, combined with structural-tectonic basis. Analysis of the card reveals two geochemical zones within the study area — the western and eastern, significantly different concentrations of platinum. The distribution of precious metals, their relationship to the physical and chemical properties of the oil fields in Orenburg Volga-Ural oil and gas province. The data obtained can be used in metallogenic zoning of the platform and the folded Orenburg on platinoids specialization for prospective evaluation precious metals for stratigraphic correlation of oil-saturated formations and address sources of precious metals in the hydrocarbon feedstock.

METALLOGENIC ZONING OF ORENBURG PART OF SOUTH URAL BY PLATINOID SPECIALIZATION [№ 6 ' 2015]
Precious metals play an important role in science and the national economy. The increasing rate of consumption necessary to review the structure of the raw material base of platinum group metals and gold. Address this issue and the subject of this study, which attempts to investigate the regularities of spatial distribution of Pt, Pd, in association with Au and Ag over a wide area of Orenburg in the Urals. To solve this problem, analyzed samples from 17 industrial types of deposits of Orenburg region by a single method with the use of the author's patented method for determining this metals. The resulting array of data formed the basis of the interpretation of geochemical data, during which the parameters were defined platinum group specialization sulphide deposits (gold, copper massive sulphide, copper sandstones), deposits in the ultramafic complexes and established an independent distribution of palladium in this group metals, that allowed the use of the ratio of Pt/Pd at systematizing results, produce metal zoning studies for each of the above structural-material complexes and identify metallogenic zonation platinoid specialization geological and structural zones of the South Ural and specific industrial types of deposits and pre-assess the metallogenic potential of the territory through the use of innovative sources of precious metals.
