Abstract
The creation of the East Siberian metallurgical base is an indispensable condition for the implementation of reindustrialization processes, including industrial and civil construction, engineering for the mining industry, the chemical industry, etc. The existing opportunities are the formation of a promising heavy-duty iron ore base for the Urals and Western Siberia based on the Bakcharskoye deposit causes the creation in Eastern Siberia of mining and metallurgical enterprises, mainly of local importance. Perspective restrictions on the use of natural gas in iron production, environmental and investment restrictions for blast-furnace production determine the use of liquid-phase iron reduction technologies using thermal coals. The concentration of groups of iron ore deposits in the Irkutsk region makes it possible to create mining and metallurgical plants near the cities of Ust-Ilimsk, Taishet, Tulun. The involvement of significant resources of titanomagnetites is possible when solving the problem of developing more efficient technologies for producing metallic titanium. The object of the research is resources of iron-ore and coal deposits in the Irkutsk region in the process of assessing the possibility and efficiency of their use in the prospective mining and metallurgical industries. The subject of the research is technological and resource prerequisites for location of large objects of mining-metallurgical complexes for direct production of iron in Irkutsk region. The aim of the research is to identify promising deposits and occurrences of iron ore and coal raw materials, taking into account the possibilities of application of existing technical and technological solutions for transportation, enrichment and metallurgical processing for complex processing. The objectives of the research are: to assess the potential of large iron ore deposits of Western Siberia using new technologies to meet the needs of metallurgical enterprises in the Urals and Kemerovo region; to determine a new concept of promising metallurgical base of Eastern Siberia; to determine a promising base for the placement of mining and metallurgical plants in the Irkutsk region. Methodology and research methods. The research methodology is based on a systematic representation of the mining-metallurgical complex created on the territorial combination of raw materials and fuel in accordance with the theory of energy-production cycles, in which promising (innovative) technologies are implemented. When determining the degree of priority development of titanium-magnetite deposits, the possibility of using the resulting titanium-containing products is taken into account. It is also shown that the main metallurgical base of the Irkutsk region can be created in the area of the city of Tulun on the basis of the use of iron ore resources of the Eastern Sayan. The fuel base is provided by the resources of the Irkutsk coal basin. To reduce investment and current costs associated with the transportation of coal and ore or concentrates, it is proposed to use slurry pipelines
