FIELD: metallurgy.
SUBSTANCE: invention refers to precious metal metallurgy and can be used for industrial gold extraction. Extraction method of gold from concentrate involves cyanidation or supply of chlorine-air mixture thus obtaining cyanide or muriatic gold-containing solutions respectively. Gold is extracted from the obtained solutions by sorption or carbonisation. At that, initial raw material is concentrate of phosphorite ore of shelly type of the Baltic-Ladogian gold field.
EFFECT: enlarging deposits of mineral raw material for industrial gold extraction.
