Bentonite clay is an important natural material, widely used in many industries. The purpose of this article is to analyze the mineral resource base of bentonite clays in Russia. The data on reserves of deposits, the degree of their development and production volumes are given. The composition and uses of the main developed deposits of bentonite clay in Russia are characterized. A comparative analysis of the reserves and production growth of bentonite over the past decade is carried out. A brief description of the world situation is given, and the mineral resource base of the CIS countries is considered. Since the quality of raw materials, its properties and reserves directly depend on the conditions of origin, a characteristic of the geological and tectonic position and genesis of the bentonite clay deposits of Russia is given. Bentonite-bearing provinces with favorable conditions for the formation of bentonite deposits with volcanogenic-sedimentary genesis are considered. The most promising regions are proposed for the purposes of expanding the mineral resource base of bentonite materials. This work is the result of the authors’ own geological works at various deposits of bentonite clays in Russia, the near and far abroad, as well as the study and interpretation of published materials on this subject over the past decades.

New Occurrences

New bentonite clay deposits have recently been discovered in the state of Paraíba, mainly in the municipalities of Cubati and Pedra Lavrada, creating great expectations in view of the possibility of expanding industrial production using these new reserves. The aim of this study was to study the new occurrences of bentonite clay in Paraíba, particularly in the municipality of Pedra Lavrada, for use in water based drilling fluids. The mineralogical properties of the clays were characterized by particle size analysis using laser diffraction, and thermogravimetric and differential thermal analysis, and its chemical composition was analyzed by X-ray fluorescence, X-ray diffraction, cation exchange capacity and specific surface area. The bentonite clays were treated with sodium carbonate at concentrations of 75, 100, 125, 150 and 175mEq/100g of dry clay, to transform them from polycationic to sodium form. For the technological characterization, drilling fluids were prepared according to the standards of Petrobras. The results indicated that the mineralogical composition of the samples consisted of montmorillonite, kaolinite and quartz. As for their rheological properties, the samples were found to partially meet the rheological requirements of the Petrobras standard.

Due to the decline in gas and condensate production at the Orenburg oil and gas condensate field, the priority area of activity of Gazprom PJSC and Gazprom Dobycha Orenburg LLC is the reproduction of the mineral resource base and the achievement of maximum component recovery factors to provide the Orenburg gas and chemical complex. The solution to this problem is directly related to the involvement of the unique reserves of hard-to-recover oil (matrix oil, high-molecular raw materials), confined to the gas-saturated part of the Orenburg field, in the production and deep complex processing. Hard-to-recover oil has a variable composition – from high-bituminous oil in fractured-porous and porous low-permeability reservoirs to liquid traditional oil in porous and large-pore permeable reservoirs. This paper analyzes the results of estimating the reserves of matrix oil, the predicted resources of associated components of matrix oil (metals) and the retained gas reserves, which are not included in the assessment of reserves.

Investment Projects

The article has indicated by the problem of assessing the effectiveness of investment projects of development of mineral resource base in the face of declining quality of raw materials and the transition to the working out of deposits with low content of useful components. The problem of providing with raw materials is relevant for the ferrous metallurgy of theRepublicof Uzbekistan. The decision can be the development of a deposit of titanium-magnetite ores «Tebinbulak» with low iron content. Justification of the effectiveness of such a project requires the use of modern tools. The article has substantiated the possibility of using real options to assess the economic efficiency of investment projects to develop the mineral resource base. In this paper we have considered the concept of real options in relation to the field of investment projects to develop the mineral resource base, have developed a classification of possible options in this area. To assess the value of real option of the project of develop the mineral resources base we have proposed to use Black– Scholes model, have given the interpretation of elements of model in relation to this sphere. On an example of field development project titanomagnetite ores «Tebinbulak» has evaluated the strategic value of the project with realigning option expectations.

Reproductive Cycles

The questions of optimizing the reproduction indices of mineral and raw materials base are determined by the Budget Code of the Russian Federation and Federal Law No. 44-FZ of 05.04.2013 and are caused by a discrepancy between the economic interests of participants in the procurement process. Rosnedra, as a state customer, organizes purchases. The subjects entering into relations with the state customer in the stage of determining the supplier are legally independent geological organizations with their own means of production. The main indicator of their activity is maximization of revenue and profits from fulfillment of orders. For federal, regional and local government bodies, the goal is to maintain geological services markets, develop a regional mineral resource base. It follows that economic motivations of potential participants do not always coincide, and sometimes even contradict each other. In our opinion, one of the ways to maintain reproductive cycles of the mineral resource base is to use geoinformation systems in geological exploration modeling through the classification of methods and tools, determining composition of the modules consisting of indicators, conducting their peer review. The purpose of the study is to analyze and systematize the provisions of the contract system in the procurement segment and propose the ways to improve it, based on geological and economic monitoring, to group monitoring indicators into three interacting functional blocks within a single data warehouse: mineral resource base, mineral resource complex and mineral resources potential. The research methodology includes analysis of subsoil users operating in the region; deposits with industrial categories; deposits with geological reserves; soil areas containing predictive resources of category P1; soil areas containing predictive resources of category P2; soil areas containing predictive resources of category P3. As a result, the authors carry out an expert assessment of the limit values of indicators for the mining zones of the Bryansk region, on the basis of which it is concluded on the feasibility of use of geological and economic monitoring with respect to information support of the contract system in the procurement sphere.

The purpose of the article is using the data of Geoinform of Ukraine on the current state of the mineral resource base of the country, to regionalize its territory by combining explored mineral deposits and production-territorial complexes formed on their basis with a mineral raw material orientation. Research results. The article is written in the context of the constructive-geographical direction of studying the geography of mineral resources, which has been developing in the last decades in Ukraine. In particular, three approaches to regionalization of territorial combinations of mineral deposits are compared and analyzed: geological, economic-geographical and mining, which will contribute to their interconnection in characterizing the mineral-raw materials complexes of individual regions. The authors’ own interpretations of discussion definitions of mining terminology are proposed. Based on the results of previous studies and taking into account the current state of the mineral resource base, economic-geographical and mining zoning of the territory of Ukraine has been carried out for groups of explored mineral deposits. Within Ukraine, four mineral resource zones are allocated: Prydniprovsko-Pryazovska, Eastern Ukrainian, Donetsko-Slovianska and Prykarpatska, as well as several territorially separate structures: Zakarpatskyi, Lvivsko-Volynskyi, Podilskyi, Kerchenskyi, Krymskyi macrodistricts, Zhytomyrskyi and Pobuzkyi districts. A detailed description of the mineral and raw material specifications of these structures and their constituent parts, the features and prospects of their exploitation, the formation of territorial-production complexes of mineral and raw materials orientation are submitted. Scientific novelty. For the first time, various approaches to the regionalization of territorial groupings of mineral deposits and mining territories are compared, the basic definitions of mining regionalization are presented, and on this basis their own variant of zoning the territory of Ukraine on mineral resources is proposed. Practical value. The economic, geographical and mining zoning of the territory of Ukraine according to the forms of concentration of mineral deposits and mining areas will help create the scientific basis for optimizing the structure of the mining industry, ensuring the effective use of mineral raw materials, and developing the country's raw material complex.
