Abstract: In improving economy of the depressed regions of mining and processing ores the problem of using technogenic deposits and off-balance mineral raw materials is important. In terms of using tailings of ore production and concentration in underground winning, it proves that the use technogenic resources forms economic basis for radical modernization of technology that allows to raise production capacity of enterprise and sufficiency of using mineral resources and cover the costs on waste processing. On development of technogenic deposits the earlier lost reserves are engaged into exploitation. In the presence of power reserve, it is effective the development of safe pillars, the involvement of metalliferous stowage and off-balance reserves into the process of mining as they are uncovered and prepared and the costs on their prospecting and mining and development work have already discarded for mining the main stocks. In comparing technologies with various fullness of production from the depths the estimate of loss must be fulfilled on the basis of the lost value of minerals on a threshold price of the sector that allows to use the common criterion gain with consideration for damage from the loss of the mineral resource. Production of metals from mineral raw resources increases when using the technology of leaching out in disintegrator, providing production of metals to the norms of MPC per time less by a factor of two in comparison with agitation leaching. By producing metals from tailings the coproducts are being created: metals and nonmetals as salts and oxides, the tails of secondary processing with safe content of ingredients, desalted water, chlorine, hydrogen and oxygen improving economy. Using the tails of primary processing forms economic basis for radical modernization of technology, raises production capacity of the enterprise and fullness of using minerals and allows to warrant tail processing costs on certain conditions. Inclusion into exploitation of tailings of the first stages of deposit development that have not had commercial value before, considerably impacts on the amount of outputs and metal content in extracted ore mass. It reduces exploitation costs and improves performances of using capital investments and production assets.
