Improving the metallurgical resource base through combining ore mining technologies
Relevance. One of the challenges in the development of mining and processing technologies for solid metal resources is the insufficient use of the metal mining technologies in underground development of ore deposits. The purpose of the study. By analyzing the aspects of mining production, to determine the priority directions in the extraction and enrichment of metal ores based on the combination of technologies for the development of deposits. Research methods. Analysis of the efficiency indicators of mining production using information about the improvement of technologies in the past. Forecasting the ways of development and detailing the concept of breakthrough improvement of the processes of extraction and processing of solid geo-resources in the present and future. The results of the study. Information is provided on the completeness of extraction of metal ores from the subsurface and their use in enrichment. The importance of recycling metal-containing waste as technogenic geo-resources is shown, and the current state of this problem is characterized. A breakthrough direction of strengthening the geo-resource base of mainly non-ferrous metallurgy is formulated - the leaching of metals from ores in underground blocks and activators of the disintegrator type during the combination of traditional and new technology. The information obtained experimentally about new technologies with a description of their advantages is given. The problems of strengthening the geo-resource base of industry are formulated. Economic models are proposed to determine the efficiency of combining extraction and processing technologies. Conclusions. The assessment of the regularities of the development of technologies for the extraction and enrichment of solid metal geo-resources is possible on the basis of a comprehensive analysis of aspects of mining production. The priority direction of extraction and enrichment of solid metal geo-resources is the combination of traditional and new technologies.
