Gold and Silver Leaching by Cyanidation

What is the Effect of Aeration on Gold and Silver Leaching. Another of the prime requisites of successful cyanidation is free oxygen. Pure oxygen is too expensive to use, instead atmospheric air is the customary source of the required oxygen gas. Some interesting experiments have been conducted using Ozone but the practice has not been adopted commercially on account of the cost in the gold
