FIELD: hydrometallurgy and mining industry; ecological methods of extraction of metals. ^ SUBSTANCE: proposed method of extraction of metals from solid metal-containing materials or ores includes treatment or underground leaching-out with solution of reagent obtained by electrolysis treatment of solution containing halogenide-anion and separation of metal from this solution. Electrolysis treatment is carried out under condition of positive mass transfer on revolving electrode or on electrode moving at acceleration of no less than 0.1 m/s. After electrolysis treatment, water-soluble polymer used as surfactant is introduced into reagent solution in the amount of no less than 0.01%. ^ EFFECT: enhanced efficiency and ecological safety due to reduced power requirements, intensification of process, avoidance of toxic emissions and use of safe chemicals. ^ 7 cl, 2 dwg, 6 ex |
