FIELD: geotechnology. SUBSTANCE: the offered method includes formation of pile of complex ores on impervious base, and electrodes are placed into pile. First, potential difference is applied to electrodes and water is supplied through pipeline. After electrochemical dissolving of elements-impurities, useful components is leached. For this purpose, voltage is removed, and supplied through pipelines are solutions containing active agents. Metal-carrying solutions are collected in solution collectors. EFFECT: higher efficiency. 1 dwg
