FIELD: metallurgy.
SUBSTANCE: invention refers to method of preparing water chemical solution for washing gold out of ores and concentrates. Method involves introduction of hydroxide of alkali or alkali-earth metals, and aerial oxygen. Then there performed is electrochemical treatment of water solution of dissociating reagents containing oxygen and/or halogen in electrolyser consisting of anode and cathode chambers. At that, gas-water mixture is obtained in anode chamber and water-gas mixture - in cathode chamber at photochemical treatment of gas-water mixture obtained in anode chamber. Then after photochemical treatment, gas-water mixture is mixed with water-gas mixture obtained in cathode chamber. The obtained emulsion is subject to photochemical treatment.
EFFECT: increasing efficiency of gold washing-out owing to increase of output of active complexes.
