On the question of the feasibility of the integrated development of mineral resources of the Ural region

Abstract

Introduction. Te article deals with issues related to the integrated development of the mineral resources of the Ural region. Te integrated development of mineral deposits is a priority area for improving mining, including the maximum possible extraction of the main valuable component of the mineral, as well as the search for technical and technological solutions for the extraction of associated valuable components and marketable products suitable for the production of host rocks. Te purpose of the work is to assess the feasibility of the integrated development of mineral raw materials and the processing of mining and processing waste to obtain commercial quality products. Methodology. Associated components in processed mineral raw materials can be of industrial importance only if the degree of their concentration in the products of enrichment, metallurgical or chemical processing, as well as the technology for the subsequent processing of these products, ensure the cost-efective extraction of these components. Results. Technological schemes of possible hydrometallurgical production based on tailings of wet magnetic separation of titanomagnetite ore of scandium oxide concentrate have been developed. Te results of the study of the chemical composition of the mineral material from the dumps of the gold mining production in the city of Plast for their processing and extraction of valuable components are presented. Te results of the evaluation of the physical and mechanical properties of a number of overburden rocks of AO Uralasbest (peridotite, diorite, gabbro and serpentinite) for compliance with the requirements of regulatory documents for the production of crushed stone are presented. Conclusions. Te implementation of the proposed measures will create conditions for a more rational use of subsoil and land, ensure an increase in gross output and expand the range of commodity at existing mining enterprises without a signifcant expansion of production areas, will reduce the area of land allotment and the cost of storing rocks, increase the load on the mining and processing equipment.
