- W4319763341 abstract "The purpose and relevance of the work. The article is devoted to the urgent problem of strengthening the mineral resource base of industry by involving substandard ores and tailings of their processing in the production. The purpose of the research is to find ways to modernize field development technologies. Methodology. According to the reporting data, a critical analysis of the completeness of the extraction of reserves and the effectiveness of the applied development systems is carried out. Based on the analysis of technology options, an engineering forecast of the ways of development of depressed enterprises is made. Results and scope. A reference is given on the history of ore development in the regions. The reason for the low rates of extraction from the subsurface is the discrepancy between the x development technologies and the principles of resource conservation with the transfer of reserves to the inactive category. The role of SCGMI in the theory and practice of lead and zinc leaching is shown. The information about the project of development of a deposit of balance ores by leaching is given. A reference is given on the practice of developing the Bykogorskoye deposit by leaching off-balance ores. The explanation of the increased losses and dilution of ores and the negative impact on the environment is given. The indicators of the quality of mined ores are given. A scheme is recommended for the development of North Caucasian deposits by leaching ores in blocks and tailings of enrichment in disintegrators. Quantitative indicators of metal extraction into solution are given. The results of the study may be in demand in the extraction of metals from technologically opened ores. Conclusions. The conditions of the regions of the North Caucasus correspond to the combined technology of the development of fertilizers with the extraction of metals from rich ores at the plant and the leaching of poor ores in blocks and tailings of enrichment in activators of the disintegrator type" @default.
