The paper discusses the problems of increasing the efficiency of processing gold- and copper-containing ores of the Taror deposit. A flotation enrichment scheme for the studied ores and a phase analysis of the flotation concentrate have been developed, and the leaching of honey and gold from the concentrate of the studied deposit has been studied. The main kinetic patterns of nitric acid decomposition of flotation concentrate from the Taror deposit have been studied. The optimal conditions for opening gold- and copper-containing concentrates with nitric acid were found: nitric acid concentration – 400 g/dm3; process duration – 120 minutes; S:I ratio = 1:5.

Based on experimental data, a mathematical model has been proposed for determining the degree of extraction of this component during nitric acid leaching of gold- and copper-containing flotation concentrates from the Taror deposit. Based on scientific research, a basic scheme for processing gold- and copper-containing ores from the Taror deposit has been developed.

 

Key words: copper ore, recovery rate, flotation, duration of the process, nitric acid technology, honey leaching, empirical formula, least square method.
