Abstract

The strategy for increasing efficiency of the mining industry in Russia can be a diversification of production using metal leaching technologies, as an alternative to conventional technologies with the loss of substandard raw materials. Efficiency of in-situ leaching is studied by an integrated method, including an assessment of the quality of ore crushing and the parameters of metal extraction from ores into a production solution with driving reference workings for quantitative confirmation. Long-term industrial experiments have proved the possibility of extracting metals from substandard raw materials not only with a decrease in losses, but also with an increase in reserves due to metal-containing raw materials. The issues of the diversification of mining production based on the technology of metal leaching are considered by systematizing and detailing of the experience in a practical application of technologies with the leaching of metals in underground mine blocks. It is concluded that in order to expand the range of application of the leaching technology, the conventional technology of ore preparation for the extraction of metals in situ needs to ensure the desired particle size distribution, uniform density of ore distribution in the shrinkage stope, create conditions for filtrating leaching solution flows and prevent losses of production solutions. The obtained regularities of physicochemical processes of leaching in underground blocks, stacks above ground and in activators of hydrometallurgical plants can be used in the extraction of metals from chemically opened metal-containing raw materials. Conversion and diversification of mining production requires the development of a scientific basis for leaching, including increasing extraction from ores, ensuring the required particle size distribution, intensifying the process, etc. Thus, generalized theoretical and experimental findings obtained in Russia and abroad may be highly useful.
