Justification of Optimum Volumes of Mining and Reserves of Iron Ore for the Sustainable Development of Enterprises of Mineral Raw Material Complex

One of the most important factors in the development of the state is the attraction of investments in the real sector of the economy, especially in the mineral and raw materials sector, on which the country's mining and partly manufacturing industries are based. The mineral and raw materials complex of Russia provides more than 50% of the revenue of the budget and more than 70% of foreign exchange earnings from sales. Under whatever scenario the development of the domestic economy was built, its implementation is impossible without raw materials [1]. This applies to oil and gas raw materials, which are the basis of the country's export potential, as well as to rare-earth elements, without which it is practically impossible to build an innovative economy. The relevance of the presented research is the formation of multifactorial models of production and reserves by types of raw materials, which are characterized by the highest repayment rates in the Central Federal District (CFD). The author's methodology is universal, so it can be applied to other economic regions and to different types of raw materials.
