FIELD: metallurgy.
SUBSTANCE: invention relates to hydrometallurgical method of cleaning of gold-bearing cyanic solutions after desorption of gold from nonferrous metals before electric precipitation of gold. Method corresponds to that it is implemented treatment of solution by oxidising agent for destruction of cyanic complex of nonferrous metals and sedimentation of its compositions. In the capacity of oxidising agent it is used hydrogen peroxide with consumption not less than 4 l/m3. Treatment is implemented during 3-5 min at temperature 60 - 100°C.
EFFECT: purification effectiveness increase of solutions and receiving of concentrate of nonferrous metals for its further treatment.
