The development of mineral resources of solid mineral resources goes mainly together with problems because of natural factors, which determines current position of modern technological mineralogy. We paid particular attention to problems of mineralogical study of refractory ores of natural and technogenic genesis, associated with technical, technological and economic factors. We showed that many provisions of “Strategy for the development of Russian industry for the processing, utilization and disposal of industrial and consumer wastes for the period up to 2030” are related to the field of technological mineralogy. Intensive development and improvement of physical methods of mineralogical analysis resulted in need for their metrological support. Creation of a strict metrological basis for quality control of mineralogical works ensures the reliability of results of performed researches. The formation of new methods and techniques, both research tools and technologies for studying the composition, structure and properties of solid minerals, contribute to understanding interrelationships of mineral phases and resulting spatial and temporal patterns of coexistence of minerals in rocks, ores and other natural and technogenic formations. We considered achievements, problems and prospects for the development of technological mineralogy, an algorithm for the application of its methods and approaches in the management of complex processing of mineral raw. The main emphasis is placed on the development of scientific and methodological prerequisites for solving problem of rational development of mineral raw, the maximum possible extraction and integrated use of all minerals (both main and accompanying), expansion and strengthening of the mineral resource base in the light of the global challenges of the economic and environmental doctrines of modern civilization. The studies of complex mineral systems increasingly use information technologies “big data”. For the best solution of complex tasks of geological and technological mapping and mineragenic research, methods of remote sensing using the Landsat program are becoming popular. We emphasized importance of interactive forms and methods of teaching mineralogical research for specialists from organizations of different departmental affiliation.

Abstract It is known that nowadays one of the main problems of mining is the depletion of reserves. The researchers consider mining waste as a source of replenishment of the resource base. Disputes on the prospects for technogenic raw material processing are becoming especially relevant. The object of research chosen by the authors in this article is the technogenic neoplasms resulting from dredging and hydraulic processing of placer gold. The paper presents the results of assessing the prospects and application of the information technologies, in particular, the analysis of data from remote sensing of the Earth in the design and organization of work to involve technogenic placers in operation. It is shown that these technologies are able to increase the efficiency of work and reduce labor costs at the stage of preliminary study of potential development targets. Technogenic complexes of depleted fields are a significant reserve of the mineral resource base of gold and other precious metals. This paper presents the results of the creation of a method for expert assessment of spatial and volumetric indicators of technogenic complexes of alluvial fields and other landscape objects using remote sensing of the territory and analysis of geological information. The Kerbinsky gold-bearing region of the Khabarovsk Region was chosen as the object of research.

This study characterizes the composition, structure, and dynamics of arthropod communities associated with bat guano deposits in buildings. Guano beneath three summer roosts of the little brown bat (Myotis lucifugus) in southern New Hampshire was sampled over a 1-year period.Twelve arthropod species are reported of which most are cosmopolitan associates of dried organic matter and stored products. Included are psocopterans, beetles, mites, hemipterans, a flea, and a pseudoscorpion. These taxa function as fungivores, sarcophages, predators, and ectoparasites.These simple arthropod communities exploit a seasonally rich resource produced by roosting bats. Nycteriglyphine mites were the first free-living colonizers of fresh guano deposits and were the most numerous arthropods throughout the year. Older guano deposits and those with the most diverse resource base generally supported the greatest number of species.Seasonal changes in communities included the presence of fleas only when bats were present, a greater number but lower diversity of other arthropod species when bats were present, and a more equitable distribution and abundance of species when bats were absent. Fresh, wet guano supported higher densities of fungivorous mites and flea larvae than did older, drier guano.

Rational use of mineral resources is becoming an important task for the development and economic growth of Kazakhstan. The purpose of the research was to study the state of salt-containing raw materials to determine the prospects for rational use of mineral resources of the Dzhaksy-Klych Deposit, one of the salty halite lakes of the Aral region. Exploration studies have shown that the Deposit is layered, where the halite layer is underlain by a sulfate layer: astrakhanite, mirabilite, tenardite, located on a layer of silt, the bed of salt deposits is dark brown clays, less often - clay Sands. Mineralogically, the halite formation is represented by, %: halite – 90-96, epsomite -1,2-2,6, mirabilite -0,2-1,9, gypsum-0,2-1,4. The production of table salt results in waste containing 65.5% chlorides, 24.5% sulfates, 6.5% sodium carbonates, and 3.5% sodium silicates, which can be used for pharmaceutical and medical purposes. Bottom silty mud by its origin and chemical composition belongs to the mainland silt-sulfide type and can be used for Spa and balneological treatment. The reserves of sulphate salts in the field are significant, with the average thickness of the sulphate reservoir in the southern basin being 0.87 m, and in the Northern basin 0.91 m. Intergranular and surface brine containing sodium and magnesium chloride-sulfate salts is of particular interest. Analysis of the state of mineral resources of the Dzhaksy-Klych Deposit revealed prerequisites for expanding the range of opportunities for using salt-containing raw materials. A promising direction for the development of the mineral resource base is the production of soda based on sodium chloride, as well as the production of a commercial product based on sodium sulfate and magnesium chloride. Microbiological examination showed the presence of non-pathogenic forms of halophilic bacteria in the salt-containing raw materials, which indicates safety for use in pharmaceutical and medical practice. In the Aral sea region, there is every reason for the development of the cosmetology industry, where a wide range of cosmetology and pharmaceutical products can be produced based on a combination of salt-containing and local vegetable raw materials.

The main aspects of regional development of the mineral base of Ukraine are defined. The structure of regional development of the mineral base of Ukraine was investigated by grouping administrative and territorial units by the activity of subsoil work, by the degree of industrial development of available proven reserves of minerals, by quantity and type, by the presence of strategically important minerals. It is established that balanced development of the mineral base of individual regions is complicated by the uneven distribution of studied and forecast mineral resources within the limits of separate territories, as well as the peculiarities of distribution of consumers of mineral raw materials. The main disadvantages in the regional structure of the mineral base were identified and the main directions of their optimization were determined in order to achieve balanced development indicators. The state of national programs development of mineral base of Ukraine for period to 2010 and 2030 was adopted for the balanced development of Ukraine’s mineral base. But this program does not include the issue of the regional nature of the development of a mineral base in the conditions of decentralization, which is provided for by the Concept of reforming local self-government and territorial organization of power in Ukraine. The study of official sites of regions, cities and united communities showed a systematic absence of official regional development programs for the mineral resource base.

Non-energy resources, including critical raw materials, have limited resource base, significant dispersal of minerals and very limited possible substitution. Those resources include rare earth elements, which set directions for contemporary dynamic development of many industries. With the development of innovative technologies, the demand for essential components has grown. The use of rare earth elements to develop energy-efficient technologies is very promising, especially in wind generators and hybrid cars.</p>

<p>The current research features approaches to solving the problems associated with a decline in the development of old industrial sectors in single-industry towns (monocities, or monocommunities). The target of the study is to show the necessity of strategic approach and interaction of all management levels. Particular attention is paid to resource-dependent communities. Enterprises of mineral resources sector have limits of effective development, associated with gradual depletion of their resource base. Diversification and modernization of the economy of resource-dependent communities are logically linked to a timely achieving of strategic objectives to ensure their long-term sustainable development. Strategic aspects are also important for development planning in the sphere of new raw material deposits. A comprehensive analysis should help avoid the risks of creating new monocommunities with a poor prospect of long-term development. The article includes an analysis of international experience of Germany, Canada, and China. It is shown that a progress in solving the problems of company towns heavily depends on a strategic partnership between the federal, the regional, and the municipal governments, as well as on their collaboration with business. A conclusion is made that a uniform strategy for the development of various single-industry towns does not exist. The choice of the way of the development for each particular monotown is determined<br />by its socio-economic characteristics. Among those, remoteness or proximity to large urban agglomerations, industry affiliation and prospects for the development of the cityforming<br />enterprise, opportunities for economic diversification, investment potential and opportunities for attracting investors are of paramount importance. The process of positive changes, as a rule, is slow and complicated. Thence, it is important to justify the purpose and ways to achieve it. As a rule, extrapolation methods do not work in this case</p>

Intensive Development

Intensive development of the mining and metallurgical complex results in considerable volumes of waste materials, more than half of which are produced by mining enterprises. Modern mining and processing can provide non-waste production only if mineral extraction and grade recovery from natural and technogenic mineral materials are regarded as a single technological process and the Earth surface preservation becomes a priority in determining parameters of process integration. The research is aimed at improving of the technology of metal leaching in a disintegrator through complex application of metallic ore concentration tailings. A radical step of reducing mining waste hazards is their utilization through introducing technogenic reserves of metallic ore concentration tailings into production, thus creating a new raw material base for the mining industry. Substantiation of the concept of non-waste utilization of off-grade mineral materials depends on the amount of integration of chemical leaching and mechanochemical activation in the disintegrator and is achieved by means of modern information technologies.

Basic Characteristics

The Strategy for the management and utilization of mineral resources of the Republic Srpska includes inevitably the mineral resource base as an essential element of material and social development, and it is one of the significant reliance forms on its own suorces in achieving economic development. In this sense, geological exploration, like an important activity in providing mineral resources for the development of the economy of the Republic Srpska, has not been given adequate attention since the 1990 and has not been systematically conducted at all. The practice of the surrounding countries, and also in the earlier period, in these regions was such that geological exploration were treated adequately with the importance of mineral resources and, accordingly, funds were provided for their financing by the state and also by users of mineral resources. Today, there are no systematic geological surveys in the Republic Srpska and no systematic sources for their financing. The geological research activity in Bosnia and Herzegovina and the former Yugoslavia, throughout the earlier period, was characterized by relatively good organization and coherence of the research program. Due to this, many remarkable results have been achieved, which justify the realized investments in many ways. The paper presents the basic characteristics of the mineral raw material base of the Republic Srpska, as then an analysis of inefficiency and stagnation in the research was done, and finally suggestions are given the necessary activities to improve the present situation.
