FIELD: chemistry.SUBSTANCE: method includes application of active soda solution, subjected to electrochemical and/or photoelectrochemical processing, and leaching by supply of leaching solution, containing complexants for gold, for its extraction. Hydrogen peroxide is introduced into soda solution after electrochemical processing with obtaining active carbonate-peroxide solution. After that obtained active carbonate-peroxide solution is supplied into gold-containing mineral mass, carbonate-peroxide solution being supplied cyclically, alternating with cycles of supply of leaching solution, until acceptable level of gold extraction is achieved.EFFECT: increase of process efficiency due to formation of mineral mass of raw material more permeable for leaching solution.2 cl, 1 dwg, 1 ex |
