| Annotation | The complexity of the priority deposits of Transbaikalia determines not only their value, but also the persistence (difficulty of enrichment) of ores, which negatively affects the investment attractiveness of the region. The article reflects the main results of the research of the academic division created by the Transbaikal State University – Chita branch of the Mining Institute, SB RAS. The basic focus of which is the use of innovative geotechnological processes of selective leaching from resistant ores and technogenic-transformed mineral raw materials of valuable components. Activation leaching of valuable components with solutions and water-gas emulsions, prepared by electrophotochemical stage treatment of initial aqueous solutions of the corresponding reagents, significantly increases the extraction of encapsulated and dispersed gold (about 25…55 %) relative to the control scheme of standard cyanidation, as well as by at least 10…15 % of molybdenum, copper, tungsten, and rare earth elements. At the same time, such a solution prepared in electrochemical and photochemical reactors of a certain design is used in pile, vat, borehole and other systems. Use of activated solutions and water-gas emulsions in addition to direct drip irrigation of the mineral mass it is also effective for pelletizing flotation tails, cyanidation cakes, and gold-arsenic stubs. The kinetics and dynamics of activation high-speed leaching of gold, as shown by numerous experiments and pilot tests, differ favorably from standard schemes. Moreover, the main amount of the valuable component is extracted at the stage of diffusion oxidation – selective dissolution after impregnation or pelletizing of the mineral mass |
