Kurylo M. Resource constraints in the development of iron ore deposits in the transition to quality metallurgy and renewable energy

The dissertation is devoted to the substantiation of the main directions of development of the domestic iron ore raw material base and the determination of the limited geological and industrial parameters of the profitable development of iron ore deposits. In terms of the number of mineable reserves, Ukraine has long been one of the ten largest countries in the world, but the quality of domestic ore deposits is below the average among the main producers of iron ore. This is due to the involvement of a significant proportion of poor ores - ferrous quartzites, which need to be enriched. The dissertation proposes the main directions of development of the domestic iron ore complex, which as a result improve the quality of iron ore raw materials. For iron quartzite deposits it is technological modernization and optimization of ore dressing schemes, improvement of source ore quality due to optimization of conditions for delineation of balance reserves, restoration of preserved underground mining facilities for extraction of quality reserves, development of new explored and searched reserves for underground conditions. For deposits of rich iron ores, these areas are as follows: o valuation of the industrial value of reserves at considerable depths, creation of new and renewal of existing means for extraction of existing balance reserves, assessment of the industrial value of related minerals, including ferrous quartzites. For each of the proposed options for the development of deposits, detailed sales schemes were developed and consolidated technical and economic calculations were made, which allowed identifying the most effective areas in terms of their cost and timing of implementation.
