KINETIC STUDIES OF AMMONIUM CYANIDE GOLD LEACHING

The article presents the results of kinetic studies of ammonium cyanide leaching of gold ores. Ammoniacal cyanidation process used in the leaching of gold hard materials containing copper, is very complex. The problem of this method is the difficulty of selecting optimal conditions for the extraction of gold due to different interpretations of the chemistry and mechanism of reactions occurring in the leaching process that satisfies the requirements of the process. In this regard, on the basis of kinetic experiments and calculations in this work, the optimal parameters of ammonium cyanide leaching were determined.
