“…It reduces the costs of prospecting and exploring new deposits, frees up wasteland, and eliminates sources of environmental pollution. The study results of the development trends of the mineral resource base coincide with the results of studies of experts [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34].…”

The article aims to substantiate the tendency to solve the problem of the mineral and raw material base of non-ferrous metals due to the involvement of technogenic origin in substandard metal-containing raw materials. Critical analysis and systematization of new information on the current state of the mineral and raw materials base of non-ferrous metals and the environmental problems of mining associated with it. New data on the recovery and loss of metals in the process of ore dressing are presented. It is shown that the total value of metals in waste is comparable to the value of potential mineral resources in the bowels. The problems of the use of mining waste should be solved in a single package with environmental problems by creating a single technological cycle for the extraction and processing of industrial minerals of industrial waste, the use of which can make the development of industrial deposits economically viable. The practical significance of the work lies in the possibility of using best practices for non-ferrous metallurgy enterprises that are searching for ways to survive in the conditions of the establishment of market relations.

“…The concept of sustainable development of mining enterprises involves the development of technologies aimed at low-waste development of solid mineral deposits [1,2] and the maximumextraction of metals from poor off-balance ores [3][4][5], taking into account the required environmental standards [6,7]. In practice, various technologies have been tested for extracting noble metals from ores [8][9][10], including heap leaching (HL), which is a promising and relatively cheap technology for processing poor and off-balance ores containing gold, silver and other useful components [11]. The effective extraction of useful components in this technology depends on the conditions of solution percolation through the ore stack [12,13].…”

There are the results of a study of the factors determining the formation and changes in the filtration properties of a heap leaching stack formed from pelletized poor sandy-clay ores. An analysis of methods of investigation of filtration properties of ore material for different stages of heap leaching plots functioning is carried out. Influence of segregation process during stack dumping on formation of zones with very different permeability parameters of ore has been established by experimental and filtration works. The construction and application of a numerical model of filtration processes in pelletized ores based on laboratory experiments is shown. By means of solution percolation simulation at different irrigation intensities the justification of optimal stack parameters is provided in terms of the geomechanical stability and prevention of solution level rise above the drainage layer.
