FIELD: metallurgy.
SUBSTANCE: procedure consists in electro-chemical treatment of water solution of primary actively dissociating reagents containing oxygen and/or halogen in membrane electrolyser with formation of gas-water mixture. Also, mineral acids or hydroxide of alkali or alkali-earth metals and air oxygen are introduced into water solution before electro-chemical treatment. Upon electro-chemical treatment gas-water mixture formed in solution or pulp is subjected to ultra-sonic processing.
EFFECT: raised efficiency of synthesis of leaching agents due to increased output of active components.
