This paper concerns problems related to the mechanical processing of mineral raw materials. The aspects explored were limited to the analysis of comminution technologies in terms of their effectiveness and energy consumption, modeling and simulation approaches, the assessment of crushing results, and environmental aspects. This article includes investigation of new technologies of comminution, comparing HPGR, high-voltage pulses, and electromagnetic mills. In the area of modeling and optimization, special attention was paid to the approximation of the particle size distribution of crushing products by means of Weibull, log-normal, and logistic functions. Crushing products with an increased content of fines were well characterized by Weibull’s distribution, while log-normal function adequately described HPGR products with a relatively low content of fines.

Potential and opportunities for cassava development are still very broad along with development of companies in livestock, processed food, and other industries. Added value of cassava commodities resulting from development of downstream industries (processed products) is far higher than upstream industries (primary products), so that development paradigm in agriculture sector in future should be directed towards product expansion including its waste. This study aims to examine the economic value of cassava as a future crop from direct as well as by-products and their development strategies. Data was collected from small-scale tapioca flour farmers, ranchers and entrepreneurs. SWOT analysis was used to determine relevant development strategies. Analysis shows that cassava has an potential, especially as a raw material for food and feed industry. In short term, developing cassava strategy as an industrial raw material is to use new technologies i.e. varieties and cultivation techniques for planting arrangements. Cassava potential economic value is relatively high in terms of farming aspects, food raw materials, feed and industry. This potential, apart from main product, is also by-product that has been neglected at 29.7% of cassava main value. By-products potensial has not been used optimally and a bioeconomic value of biomass that can support integrated agriculture in the future.

The Impact

Numerous studies demonstrate that the goals of economic growth frequently take precedence over addressing social problems and problems of environmental degradation. The manifestations of this imbalance differ from country to country depending on the stage of development of the productive forces, and institutional framework that ensures the creation and adoption of new practices and approaches to exploitation of natural resources. This problem is entirely inherent into the economies of resource regions. The paper aims to examine the impact of the extraction of raw materials demanded by the national economy on the problems and prospects of the long-term sustainable development of northern Russian localities. Methodologically, the research rests on the theory of inclusive development and evolutionary economic geography. The comparative analysis of the formation of local budgets and dynamics of the Okrug in Russia reveals that the degree of their financial sufficiency depends insignificantly on the scales and dynamics of raw material production. The legislation on assigning revenues to local budgets takes into account the specifics of the northern oiland gas-producing territories rather poorly. The financial capabilities of local communities do not allow handling existing ecological problems. The growth in hydrocarbon production in current institutional conditions does not guarantee sustainable long-term development for such territories. Addressing environmental issues requires instituting serious changes at federal and regional levels, including making the alterations to the articles of the Tax Code of the Russian Federation. It is also crucially important to give financial incentives to introduce new technologies, provide research grants, lower labour taxes, and raise taxes on the use of natural resources.

The author considers the factors and difficulties of involving raw materials in international trade at the present stage. The necessity of developing new approaches to assessing the possibilities and effects of including resources in the global turnover against the backdrop of globalization challenges is shown. It is noted that the transformation of the model of world economic development reinforces attention to the resource supply factor of the modern world economy and helps to increase its role in the field of interaction of economic and political power vectors. It is determined that the technology of resource management in the global economy provides for the optimization of the processes of forming the resource base and improving the management of resource flows. It has been revealed that the problem of finding new approaches to improving the management of resource 159 МИРОВАЯ ЭКОНОМИКА И МЕЖДУНАРОДНЫЙ ОПЫТ flows, especially raw materials, in the modern world economy is becoming particularly relevant against the background of the emergence of new technologies in resource extraction, the introduction of innovations in organizing the delivery of resources to their places of consumption and reducing the efficiency of existing business models. Some aspects of the application of soft calculations and measurements in the management of raw resource flows are presented. The characteristic is given to the system of socio-economic ratings of countries. The ratings that evaluate the raw material resource flows are considered. Combined ratings are proposed for use in the management of raw material resource flows. It is noted that the competitive advantages of the economies of countries, integration associations, individual areas of production in modern conditions largely depend on their involvement in the processes of international specialization. It is posed the problem of effective countries supplying raw materials for participation in value chains. Particular attention is paid to identifying opportunities for improving the activities of Russian companies in world commodity markets.

Extractive industries often cause serious environmental harm, and even social harm, to the local populations of the commodity regions, especially in the Global South. The increasing demand and extraction of raw materials needed for the production of new technologies in the Global North is a specific case of this, which emphasizes asymmetrical global economic conditions. This article describes these harmful commodity relationships and presents the meaning behind the increase in the demand for and production of raw materials. The case of lithium is offered as an example of this development. Further, in the article, it is suggested that the lack of regulation and control promotes a series of deviant and criminal practices which can be systematically organized for criminological analysis. The harm caused by this industry, by its part, is presented as well, as well as a first categorization of its impact on the local population even in terms of human rights violations. Instead of a conclusion, an invitation to the study of these renewed forms of exploitation and victimization is made to criminologists, and especially, to criminologists from the particular regions that benefit from the development of new, innovative “clean” technologies.

Characteristic changes in the constitution of hard coals (such as the nature and abundance of functional groups, the degree of order and the development of capillary structure) that occur in coalification and carbonization processes have a profound bearing on the rational utilization of coal in the coke and carbon industries. For blastfurnace coke manufacture the selection of blend components and their influence on the development of coke structure are very important. Modification of coke structure by additions of bituminous substances of coal and petroleum origin to blends opens up the possibility of preparing synthetic coking coal. In formed coke production, the nature of coal and binder and their distribution within the mixture are significant. The use of hard coals and their extracts and pitch as raw materials for improved carbon manufacture are discussed in terms of graphitizability. The adsorptive and mechanical properties of active carbons are dependent upon coal constitution and rank. It is concluded that the rapidly developing new technologies of coal utilization require a more elaborate classification system that would include the more important structural parameters of coal constitution.

Abstract The article outlines the main problems that the cement industry causes to the environment. Authors propose technological solutions aimed at resource-saving in cement production and environmental protection. The research is devoted to low-energy cement obtained on the basis of waste from processing skarn-magnetite ores. The characteristics of the composition and properties of the technogenic material are given. The authors have justified the feasibility of using skarn-magnetite ore enrichment waste as a part of a cement raw material mixture. The possibility of changing the composition of cement by reducing the energy-intensive alite phase is demonstrated. Technological and heat engineering calculations confirming the reduction of natural mineral raw materials and fuel costs in the production of cement were carried out. The processes of hydration of the developed cements have been investigated. A method for accelerating the hardening of low-base cements due to mechanical activation, the introduction of mineral additives and a modifier is proposed. The research revealed construction and technological advantages of the developed cements, which exhibit increased resistance during operation in an aggressive environment. Physical and mechanical tests of concretes made of low-base cement were carried out. The possibility of reducing the temperature during the heat treatment of concrete is proved. Physical and mechanical tests of concretes made of low-base cement were carried out. The paper presents environmental benefits of the developed cement technology.
