FIELD: metallurgy.
SUBSTANCE: method involves treatment of mineral product with iodine-containing reagent and separation of gold from pulp. At that, obtaining of pulp and treatment of mineral product is performed by adding the solution of reagent to mineral product in ratio of 0.5:1 with pulp stirring. Solution containing potassium bromide and alcoholic iodine solution in ratio of 1:2 is used as reagent. After treatment is completed, acid is added till pH=1, mixing, addition of alkali till pH=8-11 and further mixing is performed. Then, water dilution is performed so that flakes containing gold are formed and separated.
EFFECT: improving gold extraction efficiency and reducing the costs for reagent treatment.
