FIELD: technological processes.
SUBSTANCE: invention relates to the hydrometallurgical processing of gold-containing thrust materials. Method is based on the use of slightly acidic solutions of nitric acid and consists in intensifying the process of hydrometallurgical gold recovery through the combined use of ozone during the oxidation operation and of the binary complex-forming system, which consists of the amino acid and thiocarbamide during the leaching operation. Technical result is the increased efficiency of the gold recovery process by means of reducing its duration with the full extraction of gold into the solution of more than 90 %, as well as by means of reduction in the amount of the formed secondary alkali and salt wastes.
EFFECT: invention can be applied to the processing of any ore material.
