Abstract Supply chains in the mineral raw material industry take different forms depending on requirements, the placement of resources and points of consumption, and the nature of geological, morphological and botanical landscape type. Hitherto, in the context of montanistic tourism, the attention is paid primarily to the objects associated with the exploration and exploitation of mineral resources. Professionally and touristically, processes of transport of mineral raw materials and products of their processing can be interesting. Therefore, during the selection, development and implementation of montanistic tourism products, it will be useful to focus on these parts of a supply chain, especially if they are implemented in areas with high levels of geodiversity and biodiversity.

The article discusses the current state-of-the-art in the tin industry and the prospects of the Republic of Kazakhstan. The evaluation is performed in terms of the development of domestic tin production for the growing global demand and the development of the domestic high-tech industry. The study includes the main domestic sources of the raw material base of the tin, which includes mineral raw materials, anthropogenic and secondary waste. Since the most important for the contemporary tin industry are mineral raw materials, the possibility of complex processing of ore from the Syrymbet deposit was studied. Based on the results of the studies performed, it was found that the mineral tin-containing raw materials of the Syrymbet deposit, in addition to cassiterite, also contain acid-soluble tin-containing minerals (stannin, etc.). At the stage of gravity concentration, the most efficient extraction performance of tin into concentrate was found for the gravity separator – amounting to 34.2%. At the leaching stage, the most efficient extraction of tin (1,543 μg/L) showed an aqueous solution of sulfuric acid with a concentration of 100 g/L, at a temperature of 45 °C.

Clustering Approach

Mineral raw materials prices have been shown to be affected by macroeconomic factors such as aggregate demand and commodity-specific factors (e.g., supply shocks). In addition, it has been shown that certain mineral raw material prices co-move, meaning that they behave similarly during expansion and contraction phases of the international business cycles. In order to assess the behavior similarity of the prices of different mineral raw materials, we propose a method that utilizes extracted features of time series price data and unsupervised learning techniques to create clusters of price movements having similar long-term behavior.

While the deposit qualities for mineral raw materials are constantly decreasing, the challenges for sustainable raw material processing are increasing. This applies not only to the demand for minimizing the consumption of energy, water, and reagents, but also to the reduction of residual materials, especially fine and difficult-to-landfill materials. Sensor‐based ore sorting can be used as a separation process for coarser grain sizes before the application of fine comminution and separation technologies and is applicable for a large variety of mineral raw materials. Sensor‐based ore sorting applies at various points in the process flow diagram and is suitable for waste elimination, for material diversion into different process lines, for the production of pre‐ and final concentrates, as well as for the reprocessing of coarse‐grained waste dumps and other applications. The article gives an overview of the development and state of the art of sensor‐based ore sorting for mineral raw materials and introduces various applications.

The article describes the modern functional and territorial structure of the economic complex of one of the most industrial regions of the Asian Russia – the Kemerovo region. The basic link in the economic complex of the Kemerovo Region is industry. A quarter of the economically active population in the region is employed in industry. Industry provides half of the gross regional product. The role of industry in the economic complex of the Kemerovo region has not changed for many years. In general, the region’s industry has a pronounced raw material orientation. Raw materials industries are the leading ones in the industry structure of the region: the total share of the coal industry, metallurgy, electrical energy and the chemical industry in the total production of industrial products is 85 %. Kuzbass is Russia’s leader in coal mining. The share of high-tech industries is negligible. Machine building accounts for no more than 5 % of industrial production. The industry of the Kemerovo region is characterized by a poly-branch structure, formed primarily on the basis of the coal resources of the Kuznetsk Basin. The leading role belongs to the coal-metallurgical system of production, which forms a number of highly developed energy production cycles (coal-energy, chemicals, pyrometallurgical and others), some of which (raw materials extraction) are located outside the region.

One of the biggest challenges for European industry is to introduce sustainability principles into business models. This is particularly important in raw material and energy intensive manufacturing sectors such as the ceramic industry. The present state of knowledge lacks a comprehensive operational tool for industry to support decision-making processes geared towards sustainability. In the ceramic sector, the economic and social dimensions of the product and processes have not yet been given sufficient importance. Moreover, the traditional research on industrial districts lacks an analysis of the relations between firms and the territory with a view to sustainability. Finally, the attention of scholars in the field of economic and social sustainability, has not yet turned to the analysis of the Sassuolo district. Therefore, in this paper we introduce the Life Cycle Sustainability Assessment (LCSA), as a method that can be a suitable tool to fill this gap, because through a mathematical model it is possible to obtain the information useful for decision makers to integrate the principles of sustainability both at the microeconomic level in enterprises, and at the meso-economic level for the definition of economic policies and territorial governance. Environmental and socio-economic analysis was performed from the extraction of raw materials to the packaging of the product on different product categories manufactured by the Italian ceramic industries of the Sassuolo district (northern Italy). For the first time the LCSA model, usually applied to unitary processes, is extended to the economic and industrial activities of the entire district, extending the prospect of investigation from the enterprise and its value chain to the integrated network of district enterprises.

Sustainable Regional Development

Climate change as well as ecological and social problems requires new goals and instruments of economic policy, based on the principles of sustainable develop­ment. However, over the past 20 years, an increase in energy prices has resulted in the raw material growth model prevailing in Russia. Has this growth led to sustainable regional development? We propose an approach to evaluating eco­logical efficiency of the Russian regions as the ratio of the output of non-primary goods and services to the input of resources (labor, capital, raw materials, and environmental costs). This is a new indicator of the quality of economic growth. The sustainable development model, combining growth of GRP per capita and ecological efficiency, has been observed for more than half of the period in most regions. The eco-efficiency of the average region has been growing since 2003, except crisis periods, following an increase of the services sector share and the closure of inefficient pollution-intensive factories. According to the econometric results, ecological efficiency was growing faster in densely populated regions with a high share of high-tech services, investment attractiveness and intensive tech­nology implementation (Moscow; Saint Petersburg; Sverdlovsk, Tomsk, Belgorod and Kaliningrad regions etc.); it decreased in most northern and Siberian regions. Great potential for raising eco-efficiency remains in most regions. In general, the results of regional development in Russia do not contradict the principles and goals of sustainable development (SDGs), although it was largely achieved due to the system of inter-budget transfers, distributing the oil rent surplus among the regions. In the future, an increase in investments in the non-primary sector, en­ergy efficiency and public transportation will be required. Corresponding changes can be accelerated in the context of an emerging economic crisis caused by the pandemic and falling oil prices.

Changes in the priority areas of financing in the field of subsurface use and their widespread reorientation to the search for alternative sources of raw materials which could ensure the development of modern high-tech industries are the promising direction for the country's growth in sustainable development conditions and Green Energy Transition. And at the moment the only resource that can ensure safe progress in the future and plays an important role in today's technological development is rare earth elements (REE). Within the framework of this study information on the current state of awareness about the REE mining prospects in Ukraine was analyzed and generalized; the systematization and updating of available data on quantitative and qualitative REE ore occurrences and deposits characteristics and their geological and industrial parameters was done; the main obstacles / barriers to the active mining development on these objects of potential extraction were identified. The obtained ranking results of domestic deposits and REE manifestations prove the expediency of investing in geological exploration and mining operations conducted in certain areas, which are identified as the most attractive for further industrial development and generally emphasize the prospects of the studied area and justify the need in intensification of selected rare earth objects field development.
