FIELD: processing ores of non-ferrous, noble and radioactive metals at industrial and non-industrial content of metals.
SUBSTANCE: ore pulp is preliminarily saturated with oxygen, after which leaching reagents and sorbent are introduced. Then, straight-flow ion-exchange sorption of dissolved components and part of leached metals is performed at removal of sorbents saturated with admixtures and metals from last Pachuca tank (pulp agitator); then, counter-flow sorption of leached metals is performed. Sorbents saturated by leached metals are removed from last Pachuca tank (pulp agitator) or from next to it Pachuca tank in way of motion of pulp. Ion-exchange resin or carbon may be used as sorbent.
EFFECT: reduction of losses of valuable metals.
