Degradation of Lithium-Ion Batteries in an Electric Transport Complex

The information about the state of the use of natural resources in Russia is given and the need to search for new sources of raw materials for industry is justified. There is a tendency to reduce the production capacity and the rate of extraction of metal ores, which does not allow the use of the infrastructure of mining enterprises and creates the problem of processing substandard ore deposits and disposal of accumulated waste. The concept of deep processing of substandard metal-containing raw materials and a strategy for the survival of mining enterprises, including the use of metal leaching technologies, is formulated. The advantages of technologies with the leaching of metals from mineral raw materials at the stages of its processing are characterized. The advantages of leaching in disintegrators are shown by comparison with the indicators of the basic variant. It is noted that mechanochemical activation improves the quality of concretes made on the basis of recycled tailings. Managing the properties of recyclable materials allows you to implement the principles of resource conservation with an economic effect. It is concluded that the recommended technology is the real direction of technological modification of production.

The article substantiates the need to strengthen the mineral resource base for the production of non-ferrous metals through the involvement in the operation of substandard raw materials, primarily those stored in tailings dumps for the enrichment of metal ores. The results of the analysis of reserves of ore deposits are presented in comparison with the situation in the world. Quantitative data on the state of the mineral resource base of non-ferrous metal ores in Russia and the provision of industry with metal raw materials are given. The role of mineral resources in protecting the geopolitical interests of Russia is shown. It is noted that Russia lags behind technologically developed countries in a number of indicators of production and consumption of mineral resources. It is concluded that the development of technogenic deposits using innovative technologies is a real step towards strengthening the mineral resource base of Russia, therefore, research on the direction of mining mentioned in the article is relevant.

“…The main results of the development of underground leaching of metals from substandard raw materials include the following provisions:  A methodology for assessing the ecological and economic efficiency of underground leaching technology and combined mining technologies has been developed.  Leaching technologies make it possible to obtain metals of higher quality, which is important when using them in related industries [5][6].…”

The results of the analysis of the theory and practice of leaching metals from substandard raw materials are presented. A brief historical reference is given on the leaching of metals from experimental leaching in the middle of the last century to industrial development in modern times. The direction of combining traditional and innovative technologies within a single technological process is formulated. The mechanism of underground block leaching of ores is described. A complex method of multi-factorial assessment of the existing natural and man-made factors of development is proposed. The parameters of the proposed technology and some aspects of its application are substantiated. Using the method of engineering forecasting, the prospects for leaching metals from substandard raw materials are assessed. The main results of the development of underground leaching of metals from sub-standard raw materials and the prospects for improving the method with the rational combination of underground leaching technologies with traditional mining technologies are formulated. It is concluded that the leaching of metals from substandard raw materials has prospects for development.
