The chemical principles of gold leaching by sodium cyanide are the following: 4Au +8NaCN + O 2 + 2H 2 O → 4Na[Au(CN) 2 ] + 4NaOH The essential requirements for a good gold recovery are adequate cyanide and oxygen levels as well as a p H – value between 10 and 12. The normal cyanide consumption per tonne of ore is in the order of 100 – 500g.
