摘要

FIELD: metallurgy.;SUBSTANCE: in preparation of mineral mass for leaching carbonate-alkaline solution is added thereto which contains diluted carbonic acid and active oxygen. Said carbonic acid and active oxygen are produced by electrochemical and/or photochemical treatment of soda solution. Besides, complexing agent and ion-exchange gold-selective resin with active oxidiser radicals and complexing ions for gold are added thereto. Note here that concentration of complexing agents in said resin is maintained larger than that in solution to process mineral mass. Then, prepared mineral mass is placed in tray with moisture proof sides and bottom and cured under moisture-proof film for sorption leaching of gold from sintered material. Note here that leaching is carried out under penetration-diffusion conditions. Then, oxygenated water or weak solution of the main complexing agent to obtain the pulp. Then, said pulp is bubbled to separate saturated sorbent therefrom.;EFFECT: higher efficiency of gold extraction.;2 cl, 1 dwg, 1 ex
