Abstract

The article is devoted to leaching of gold refractory oxidized gold ores containing copper. It is noted that the direct cyanidation of gold from similar ores is a complex problem due to high contents of copper. It is established that one of possible ways of problem solution is ammonia cyanidation. The oxidized refractory ores of the Tarror deposit is selected for investigation.
