FIELD: metallurgy.
SUBSTANCE: procedure consists in saturating pulp prepared from ore with oxygen and in introducing leaching reagents and sorbents. Further, there are performed sorption leaching with saturation of sorbent with metal impurities and partially with valuable metals, in counter-flow sorption of base part of valuable metals and in withdrawing sorbents saturated with valuable metals. Also, before introduction of leaching reagents activating solution, treated with light radiation in ultraviolet region of spectre or photo-electro-chemically treated, is introduced into pulp prepared out of ore containing valuable metals in dispersed form. Sorption leaching is carried out in electric field for electro-sorption extraction of primarily leached metals with periodic withdrawal of sorbent from zone of electro-sorbtion.
EFFECT: reduced losses of industrially valuable metals.
