Foam glass is known mainly as a cellular thermal insulation material obtained by sintering a mixture of glass powder and a blowing agent followed by annealing of the foam material. This article explores the possibility of producing heat-insulating foam glass directly from widely available amorphous-siliceous natural flasks, eliminating economically disadvantageous and energy-intensive processes of cooking and granulation of special multicomponent glass melt from the scheme of traditional technology.

Contemporary mining industry is a complex system that is constantly expanding both in terms of explored sources of mineral raw materials and in terms of developing new approaches to mining and processing of minerals. Such a buildup in the scope of tasks set for the industry, as well as the technical progress, lead to various issues related to the quality, quantity and rational use of mineral raw materials. Rationalization, in its turn, should be carried out in a phased manner through the use of comprehensive measures, one of which is reclamation of man-made wastes, represented by waste rocks, tailings, slags, dust, etc. In addition, this approach simultaneously resolves several other important challenges the industry is facing, e.g. increasing the environmental safety of mining regions and increasing the economic feasibility of production by extracting additional components from waste materials. The scope of application of such a solution to the challenge of rationalizing production is immense and can be implemented at many deposits located in the territory of the CIS due to the presence of huge volumes of waste generated by mining raw materials. These wastes were accumulated because of the absence of full-fledged technologies to extract useful components from the rock mass in the past as well as other requirements to ore conditioning than those acting today. For example, in the Republic of Bashkortostan, the overburden dumps and off-balance ores that have been created by mining enterprises amount to more than 1 billion tons, hydraulic-mine dumps of processing plants reach 50 million tons, manmade waters exceed 9 million m3 annually. At the same time, the amount of useful components contained in these man-made deposits can be up to 1.5 million tons for copper, 2 million tons for zinc, about 100 tons of gold as well as significant amounts of other associated components, including various non-metallic formations.

Technological Study

Siliceous-carbonate rocks are widespread on the territory of the Republic of Dagestan, in which the total content of zeolites and opal-cristobalite-tridymite phase (OCT) exceeds 45 %, and the content of calcite is above 30 %. The rocks, composing a productive stratum (at least, most of it), lithologically correspond to opoka-like and highly siliceous limestones, zeolite-containing (10–15 %) and zeolite (40 % or more), weakly quartz and weakly clayey. However, they are distinguished from pure limestones by a low value of actual calcite part — often less than 50 %. Therefore, in this case, the section of the productive strata is defined as «folded by siliceous-carbonate zeolite-containing rocks.» Such rocks, in accordance with the results of laboratory and technological study, are considered as raw materials for the production of building materials. Zeolite-containing rocks are suitable for use as an additive in Portland cement, which will save cement clinker in the production process and improve the quality of cement. Prospecting works for zeolites and zeolite-containing rocks in the Levashinskaya (Levashinsky district) and Rubaschayskaya (Tabasaran and Kaitagsky districts) areas of Mountainous Dagestan were carried out by the non-metallic party of JSC Sevkavgeologiya in 2007–2009. The resources of siliceous zeolite-containing rocks are in the P1 category — 49.308 million tons, in the P2 category — 69.470 million tons. The predicted resources, their laboratory and technological properties (physicochemical, chemical, technological) indicate the possibility of creating a solid mineral resource base and construction of large complexes for the extraction and processing of zeolites and siliceous rocks in Levashinsky (Levoberezhny and Pravoberezhny areas) and Tabasaran (Dyubek area) regions of the Republic of Dagestan.

The analysis of macroeconomic indicators of the results of solid mineral extraction (TPI) in 11 subjects of the Far Eastern Federal district (DFO) was performed. The total value of production of all types of minerals (DPI) in terms of money at DFO is about 2.4 trillion rubles (45% of total gross regional product (GRP) of the region is equal to 5 trillion rubles.). More than 63% of the volume of DPI is achieved at the expense of fuel and energy resources of the Sakhalin region and the Republic of Sakha (Yakutia). In the dynamics of the region, there is a significant increase in GRP, production and value added for the DPI in general, and the production of fuel and energy minerals, but slower growth in the production of solid minerals. Ore (metal) raw materials of the region’s subjects in its total GRP is about 21%, in value terms-500 billion rubles. The region produces 16-18 types of ore mineral raw materials, including 12 types of raw materials as the main components of production, 4-5 types-as associated components. The main one is gold production (in 2019 more than 170 tons), silver (more than 930 tons). In the Far Eastern Federal district, reserves and resources of the main TPI for the long term have been identified. It is possible to significantly support the mining industry of the region in the case of exploration of new deposits with high-quality ores. Ore mineral raw materials of the leading geological and industrial types are currently insufficiently studied. It is necessary to develop intra-regional use and processing of raw materials to final products, create metallurgical industries, this will give new incentives to the development of the region’s resources. The analysis is of practical importance for evaluating and selecting directions in the deposits of subsurface use.

In the Republic of Kazakhstan, the most promising are kaolinite clays of the Alekseevsky deposit. For effective processing of clays, it is necessary to develop special methods of processing, since satisfactory results were not achieved when using standard methods of gravity processing. The article provides the results of studies of the effect of preliminary chemical activation on the yield of the kaolinite fraction during gravitational processing. Previously, the method of preliminary chemical activation of raw materials in a solution of sodium bicarbonate has proven itself well in the processing of various mineral raw materials. It is determined that as a result of preliminary chemical activation, changes in the phase composition occurred. The dependence of the yield of the kaolinite fraction on the temperature of chemical activation, duration, and the ratio of W:T and the concentration of the sodium bicarbonate solution. Based on the results obtained, a technology for the complex processing of kaolinite clays has been developed, which provides for the preliminary chemical activation of the feedstock at the beginning of the process, which will effectively isolate high-quality kaolinite and quartz products, which will significantly reduce the flow of materials entering for sintering. As a result of activation, the phase composition of the kaolinite fraction has changed: the percentage of the kaolinite fraction has decreased; new phases of muscovite and sodium aluminosilicate appeared; the amount of quartz increased.

The mineral resources of the Republic of Srpska enable the exploitation and processing of mineral raw materials in the metal, metal processing, construction, chemical industry, cement industry, ceramics and construction materials, etc. The largest part (over 90% in terms of value) are reproductive materials for processing in other industries and a smaller part are products that go directly to the market. In the conditions of increasing and faster technological development and with the tendency of increasing exploitation of natural resources in the world with changes of previous life conceptions, there was a need to analyze the sustainability of the mineral resources and natural resources use for further development of the Republic. The importance of a clearly defined Strategy for Management and Utilization of Mineral Resources and Raw Materials in the Globalization and Advanced Technologies Era is shown in the paper, which would enable planning and defining the goals of the use of mineral resources, clearer identification of the potential mineral resources, and basic starting data for creating the activities in order to more rational and economically efficient management of the natural resources in the Republic of Srpska. At the global level, it has become clear that geology is a very important geopolitical factor in the 21st century. Тhe importance of disposition аnd knowing where, how many and what types of mineral resources we have, can be achieved through to the several strategic activities. The development of the Strategy for the Management and Utilization of Mineral Resources of the Republic of Srpska, the "central interactive" database of mineral resources and the establishment of the Agency or the Directorate for Mineral Resources, are some of the proposals for these strategic activities.

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.
