The purpose of the given work is to substantiate the possibilities of strengthening the potential of depressed mining
enterprises during metals underground mining by the example of the North Caucasian region. The methodology of the
given work synthesizes theory and practice of the use of technologies, experiments on metals leaching, and economic
estimation of technologies efficiency by means of comparing mineral recovery rate factor using alternative techniques.
The article substantiates the priority of combining technologies of poor ores leaching and traditional technologies of rich
ore mining. The analysis is fulfilled of mixed technologies application underground mine for commercial ore production,
which is the first of a kind in the world practice. The basis for combining traditional and new technologies of ore recovery
is examined by means of combining technologies within the limits of a single process. The model of identifying ecological
and economic efficiency of deposits exploitation is suggested; the account of the recovered resources completeness lies
at the heart of the model. The article introduces the example of determining recurrent extraction ratio when using mixed
technologies. Results field of application includes formerly subsidized mining enterprises, which develop metal ore
deposits using underground method. Revitalization of profitable metal production at depressed mining enterprises is
possible on the basis of traditional and new leaching technologies combination.
Key words: deposit; ore; metal; mixed technology; leaching; ecological and economic efficiency; conversion.
