В настоящее время в экономическом развитии не только отдельных регионов, но и всей страны особую роль играет состояние добывающей промышленности, в основном топливно-энергетических ресурсов и цветных металлов. В Российской Федерации доходы, получаемые за счет добычи и экспорта минерального сырья, в стоимостном выражении составляют около 80% российского экспорта. В статье рассматриваются экономические аспекты недропользования в северных регионах ресурсного типа, специализирующихся на добыче высоколиквидных минеральных ресурсов: нефти, газа, угля, алмазов и золота с целью выявления сильных и слабых сторон. Анализируются минерально-сырьевой и производственный потенциалы добывающей промышленности регионов. Методом математической статистики оценивается уровень зависимости социального развития регионов от добывающей промышленности по шкале Чеддока. На основе факторного анализа и оценки экономических составляющих недропользования и региональной статистики за 2010-2020 гг. выявлены высокий уровень ресурсной ориентированности экономики, капиталоемкости и фондоемкости добывающей промышленности и моноспециализация экономики во всех северных регионах ресурсного типа, высокий уровень зависимости социального развития от добывающей промышленности в Республике Саха (Якутия), Ханты-Мансийском – Югра и Ямало-Ненецком автономном округах. Выделены негативные и позитивные факторы устойчивого развития добывающей промышленности, также определены ключевые моменты перспективного развития экономики северных регионов ресурсного типа. At present, the state of the mining industry, mainly fuel and energy resources and non-ferrous metals, plays a special role in the economic development of not only individual regions, but also the whole country. In the Russian Federation, revenues derived from the extraction and export of mineral raw materials in value terms account for about 80% of Russian exports. The article discusses the economic aspects of subsurface use in the northern resource-type regions specializing in the extraction of highly liquid mineral resources: oil, gas, coal, diamonds and gold in order to identify strengths and weaknesses. The mineral raw materials and production potentials of the mining industry of the regions are analyzed. The method of mathematical statistics evaluates the level of dependence of the social development of regions on the extractive industry on the Cheddock scale. Based on a factor analysis and assessment of the economic components of subsurface use and regional statistics for 2010-2020, there was revealed a high level of resource orientation of the economy; capital intensity of the mining industry and monospecialization of the economy in all northern resource-type regions; a high level of dependence of social development on the extractive industry in the Sakha Republic (Yakutia), Khanty-Mansiysk-Yugra and Yamalo-Nenets Autonomous Okrugs. The negative and positive factors of the sustainable development of the mining industry are highlighted, and the key points of the prospective development of the economy of the northern regions of the resource type are also identified.

Abstract The article presents the history of collecting data on mineral raw materials export and import in Poland and balancing mineral raw materials resources. The methodology of gathering data was analyzed on the basis of the publication “The Balance of Mineral Resources Deposits in Poland”. This is the current title of the yearbook, the back issues of which are collected in the Polish Geological Institute-National Research Institute headquarters. During the last decades the institutions responsible for collecting and delivering data have changed and they were cited in the article along with the names of general editors of the publication and the authors of the chapter devoted to the exports and imports. As a result, data on mineral raw materials international trade have been presented every year. Moreover, the scope of data and the manner of their presentation were covered in the article. The information on Polish export and import of mineral raw materials has been compiled since the 1960s. Significant changes took place for more than 50 years not only within Polish but also in the world economy, and these economic conditions – the growing number of trade partners, changes in accounting for commodities or currency changes – were the main factors influencing the successive conversions of data presentations. The range of data grew significantly, the source of data altered several times and the methodology of data presentation changed a lot. Over time, there were data presented in longer hindsight and not only on exports and imports but also on the turnover balance. The balance is treated as a reflection of the domestic mineral raw materials sector and of a situation in world mineral economy. Thus, tendencies in the trade turnover have been presented for the last 30 years, for export, import and balance. Graphs were also included in the article showing such changes in relation to the value and magnitude of the trade turnover for all mineral resources and for particular groups – energy, metallic, chemical and rock raw materials. The most important raw materials – in terms of affecting the total balance in Poland – were also specified in the article.

The purpose of the study is to conduct experiments in order to determine the possibility of technogenic gold-bearing raw material cyanidation using ultra-low concentrations of NaCN. Experiments are carried out on the cyanidation of three samples of technogenic raw materials of different composition. The first sample consists of pyrite cinders (Au - 1.8-2.3 g/t, Ag - 13-22 g/t, Fe - 48.52%, Cu - 0.15-0.30%, Zn - 0.3-0.6%). The second sample is represented by the aged tailings of copper-zinc flotation (sample I) with the content of Au - 0.8 g/t, Ag - 7.0 g/t, Fe - 17.2%, Cu - 0.212%, Zn - 0.207%. The next object is the copper-zinc flotation tailings of a concentration plant (sample II), with the following content of Au - 1.22 g/t, Ag - 15.2 g/t, Cu - 0.13%, Zn - 0.23%. It is recommended to use an aqueous wash from non-ferrous metals with subsequent lime treatment as a preliminary processing of pyrite cinders. Cyanidation is carried out at different consumptions of reagent: from 0.075 to 3 kg/t. The experiments have shown that gold recovery in this range of NaCN consumption varies from 42.9 to 44.2%; moreover, a decrease in the reagent consumption allows to reduce the concentration of non-ferrous metal ions in cyanidation solutions. Before cyanidation sample I has also been subjected to aqueous wash to remove acid and non-ferrous metals. NaCN consumption varies from 0.25 to 2.2 kg/t. In this case the extraction of gold amounts to 36.6-46.4%. Cyanidation of tailings (sample II) is carried out in the range of 0.15-1.2 kg/t of NaCN. Gold recovery varies from 24.1 to 30.9%. The cyanidation technology of technogenic raw materials in the field of ultra-low concentrations of sodium cyanide is promising, since it provides acceptable gold recovery under low reagent consumption. For further research in the field of development of an extraction technology of valuable components, the flotation tailings of copper-zinc production (sample II) are chosen as a promising object. It is planned to carry out semi-industrial tests, calculate technical and economic indicators and develop process regulations.

Abstract Today, the waste of the mining industry is more than 8 billion tons. Analysis of the literature data showed that most of the man-made waste that is generated as a result of the development of mineral deposits is suitable for use in many industries, in particular, in the production of building materials. The use of technogenic raw materials allows us to solve the following tasks: Environmental aspect - reducing the number of dumps and reducing their volumes. And this, in turn, improves the ecology of regions and territories. 2. Economic aspect - reducing the cost of construction products through the use of almost free raw materials, the release of more competitive products. Of course, it is necessary to provide that part of the costs will be spent on additional processing, revision, activation, modification of this technogenic raw material component. But today we have to think about how to clear the territory of substandard “waste rock” and use it to reduce the production and consumption of natural raw materials. A similar process can create waste-free production.

The Impact

The article is devoted to the issue of the possibility of economic development of the mining industry in the subjects of the Far Eastern Federal District (FEFD) and the impact of investment projects. With the vast wealth and diversity of mineral resources, their involvement in the national economy is an essential factor in the industrialization and successful development of the regions. In the case of the establishment of processing plants, for a number of minerals, the region could provide its own needs, as well as the countries, finished products from it, and develop an export focus. The article considers the export orientation of the mineral and raw materials complex of Russia and the constituent entities of the Russian Federation, as well as the commodity structure of exports of the regions of the FEFD. Special attention is paid to the implementation of major regional investment projects, which are important for the development of the regions. So, it is proposed to implement a major project in the form of an integrated mining and metallurgical complex due to the fact that the region needs its own ferrous metallurgy. The calculations carried out (in various versions: basic, in the conditions of the territory of advanced development (TAD), without the costs of infrastructure creation) showed that the implementation of the project is cost-effective, but due to the high costs, the support of the state is necessary.

This paper summarizes the findings of the research aimed at the development of a new method for the integrated processing of naturally occurring and anthropogenic rare-earth raw materials based on the decomposition of rare-earth element (REE) concentrates in the presence of sulfocationite. Sorption and desorption of REE cations on a strongly acidic ion exchanger, sorbent regeneration, and REE recovery from eluates are discussed. A virtually zero-waste integrated process for apatite concentrate is proposed. The generalization of the research findings is aimed at demonstrating the prospects and universality of the proposed resource-saving and environmentally safe approach to the processing of various types of naturally occurring and anthropogenic rare-earth mineral feeds. The new methodology made it possible to develop a number of new hydrochemical processes united by a single approach, providing a qualitative increase in the processing performance of various types of rare-earth mineral feeds. The theoretical foundations of a unified approach to the processing of a wide range of minerals can significantly accelerate and cheapen the implementation of specific process circuits, significantly reduce reagent consumption and waste generation, simplify the separation of rare earth elements and impurities, and the separation of rare earth elements from naturally occurring radionuclides, fluorine, and phosphorus. The study was funded by the Kolarctic CBC 2014-2020 program, Project KO1030 SEESIMA — Supporting Environmental Economic and Social Impacts of Mining Activity.

In recent decades, the global processes of technological development of industry, due to innovative modernization, have become comprehensive, affecting both manufacturing and raw materials industries. One of the components of global technological modernization is technological convergence – the combination of technologies from different industries, resulting in a inter-industry genesis of new production methods. Despite the fact that technological convergence is transforming, first of all, the industries associated with the deep processing of raw materials and highly intelligent intangible production, mining industry is in the greatest need for modernization. This is due to turbulent demand and volatile prices for mineral resources in the global market, with the widespread introduction of energy and resource saving technologies. Therefore, the mining sector of the Russian economy is looking for a "fulcrum" in initiating the diffusion of convergent technologies in mining and management processes of industrial enterprises. This "fulcrum" is intended to be the National Technology Initiative, the key target markets of which are fully consistent with the technological requirements of the Russian mining complex.
