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 problem of depletion of available mineral resources is identified and the reasons for its actualization are characterized due to incomplete extraction of metals from mined ores. It is noted that the strategy of the mining industry may be the use of unconventional technologies of metal extraction within the framework of combining traditional technologies with innovative leaching ones. It is proved that utilization of enrichment tailings, formation of the processes algorithm and engineering forecast of the prospects of the new technology are the real directions of mining production development. The paper considers a method of experimental substantiation of the possibility of waste-free utilization of ferruginous quartzite dressing tailings from the Kursk Magnetic Anomaly. The planning matrices and the results of comparing the technologies of traditional leaching of dressing tailings in conditioners and leaching in a high-speed disintegrator mill are presented with regression analysis of experimental data and graphical interpretation. A reference is given on the processes of mechanical activation, as a real opportunity to improve the indicators of the processing metal-containing raw materials, including involving dressing tailings in production. The experimental results obtained can be used in hydrometallurgical processes, including leaching of metals from dressing tailings, increasing the extraction of metals with a higher content. The paper considers the data on the metals content in secondary tailings after leaching in a disintegrator with mechanochemical processes activation. The directions of improvement of preparation of metal-containing raw materials for leaching in conditioners – disintegrators are indicated. The economic efficiency of waste-free disposal of dressing tailings is composed of the cost of extracted metals, raw materials for related industries and reducing environmental damage from the storage of toxic tailings of primary processing.
