FIELD: metallurgy.
SUBSTANCE: method for extracting metals from depulped ores involves crushing, ore depulping in leached solution and sorption of metal. Leaching is performed in ultrasound pulp cavitation mode. Metal sorption on ion-exchange resin is performed from pulp filtration solution in intensity field of alternating current in sorption activation mode of extracted metal and suppression of sorption of impurities. At that, polarity of electrodes is constantly changed to avoid deposition of metal on cathode. Leaching and sorption of metal is performed in a unit providing solution circulation till the specified completeness of leaching from ore and its complete sorption on ion-exchange resin is achieved.
EFFECT: improving metal extraction intensity.
