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.

High Yielding Varieties

New varieties of leguminous plants expand the range and improve the quality of healthy food products. The new legumes meet the requirements of modern food production. In addition, they demonstrate low inhibitory properties and possess a high phytochemical potential. Domestic non-GM peas and beans have a high nutritional and biological value; they are cheap, highly profitable, and can be produced in large volumes. Thus, they have a high potential for expanding the raw material base of the food industry. The Republic of Bashkortostan is the leader in pea production: the State Register of Breeding Achievements contains over 10 varieties cultivated by Bashkir scientists. Researchers of the Omsk State Agrarian University have created high-yielding varieties of beans with improved consumer qualities that are adapted to Siberian environment. However, the qualitative indicators of the new varieties remain understudied. The present research expands the raw material base for the production of healthy and functional foods with the new legumes adapted to the conditions of West Siberia and the Urals. The study features the characteristics of legumes of Siberian and Ural ecotype, which helps to expand the information database on the phytochemical potential of the new varieties. The beans were provided by the Omsk State Agrarian University, the peas – by the Bashkir Research Institute of Agriculture (harvest of 2018). The main objectives of the study were to determine the indicators that form the nutritional and biological value of the raw materials: protein content, dietary fiber, the presence and quantity of macro and microelements, enzymes, and trypsin inhibitor, also during germination.

The state of the created uranium raw material base, which is the basis of nuclear energy of Ukraine, is characterized. The structure of reserves and resources of uranium ores of domestic objects is analyzed. The state balance accounts for 17 deposits, most of which are represented by low-yield albite-type ores. The level of industrial development of explored uranium-containing objects is considered. At present, the mining industry exploits 4 objects of uranium-sodium formations, which provide only a share of the state’s nuclear power needs. National plans and programs foresee an increase in annual extraction of uranium ores to 3520 thousand tons. Such pace of explored stocks will last for at least 50 years. To expand and strengthen the mineral-raw material base and to achieve the energy independence of the country, it is necessary to replenish it with rich highly profitable ores, the prerequisites of which detection are available within certain promising areas. Provided data on mineral resources and production of uranium in other countries. Ukraine’s place in the world’s balance is shown.

For centuries, ceramic brick is the main building material in the construction of low-rise residential buildings and utility rooms. In addition, durability, high artistic features and the absence of toxicity characterize building ceramics. The volumes of construction in the Republic of Sakha (Yakutia) and the demand for bricks are increasing every year. Ceramic brick imported from outside the republic is used in the construction of facilities in Yakutsk. The Republic of Sakha possesses a good raw material base of clay and loam for the production of ceramic products. The study of basic properties of clay raw materials for obtaining a quality product is of particular importance. The results of studies on the use of raw materials from the Sannikovskoye clay deposit located in the Republic of Sakha (Yakutia) for the further production of ceramic bricks are presented. The chemical and mineralogical compositions of the clay raw materials are determined. Compositions of ceramic masses with the addition of waste cullet in different percentages are designed to reduce the amount of solid waste. The cullet used is tare and transparent. The technological and basic physicomechanical properties of the obtained samples are investigated.

Currently, the establishment and maintenance of management accounting is one of the priority conditions, which enables the Heads of enterprises to make timely decisions in the field of management. Directions of development, production capacity, types of produced products – all these parameters require analysis, systematization and accounting. The responsibility of all levels of administration for the efficiency of production, economic and financial activities is increasing. The authors studied the procurement process at sausage production enterprises, including the procedures for the purchase, delivery, acceptance, storage and pre-sale preparation of products. It has been determined that the following factors influence the organization of accounting system in this industry: finished products are obtained as a result of processing of primary raw materials; features of technological process depend on the type of raw materials, recipes; sausage production is distinguished by high level of mechanization and automation. The conducted studies show that management accounting does not always ensure the fulfillment of all tasks assigned to it. According to the authors, they can be supplemented with the following list: provision of information on the availability of raw material base; formation of budgets and forms of management reporting for raw materials supplied by the customer; control over compliance with sanitary and hygienic standards, quality of raw materials and finished products; providing data on product line, availability of ecological packaging. The solution of these problems contributes to the increase in the efficient and effective management; reduction of labor costs for executives and managers who make decisions on information and settlement processes.

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.

To use effectively internal raw material base, JSC “Ural Steel” accomplished I category major overhaul of the blast furnace No. 2. The main purpose of the overhaul was to design a rational profile which could ensure an ability to operate with a charge containing 95 % of Mikhailovskii GOK (mining and concentrating plant) pellets having basicity of 0.5 by CaO/SiO2. The blast furnace No. 2 having useful volume of 1232 m3, was constructed by design of Danieli Corus, the Netherlands, and was blown in on December 30, 2020. In the process of guarantee tests, step-by-step increase of Mikhailovskii GOK pellets (Fetotal = 60.5 %, CaO/SiO2 = 0.5) content in the charge iron ore part was being accomplished from 55 to 95.1%. Charging of the blend containing pellets in the amount of 55% of iron ore part, was done by charging system 4OOCC + 1COOCC (Ore - Coke) with filling level 1.5 m. Under conditions of pellets part increase in the blend, the charging system was changed to decrease their content at the periphery, to increase it in the ore ridge zone and make it intermediate between periphery and the ore ridge. At the pellets share in the iron ore raw materials 0.75 the charging system was used as the following: 3OOCC + 1COOC + 1COOCC, while at the content 95.1% the following charging system was used: 2COOC + 2COOC + 1COOCC. It was noted that in the period of guarantee tests the furnace running was smooth. The average silicon content in the hot metal was 0.70% at the standard deviation 0.666. Sulfur content in the hot metal did not exceed 0.024%, the blowing and natural gas consumption figures were 2100 m3/min and 11000 m3/min correspondently, oxygen content in the blowing 26.5%, hot blowing and top smoke pressure figures were 226.5 and 109.8 KPa correspondently. The productivity of the furnace was reached as high as 2358 t/day at the specific coke rate 433 kg/t of hot metal. After guarantee tests completion, the pellets content in the iron ore part was decreased gradually from 95 down to 50%. The decreasing was made by 5% in every 6 hours of operation. Application of the mastered technology of the blast furnace No. 2 with the increased share of pellets will enable to stably supply the blast furnaces No. 1, 3 and 4 by iron ore raw materials in the proportion of 30-35% of pellets and 65-70% of sinter.
