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

Overall, the cyanide process is very efficient. A gold ore containing less than one gram of gold per ton can, in some cases (and depending on the gold price), be profitably treated. A modern cyanide mill recovers or extracts 95% to 98% of the gold in the ore. In a cyanide mill, lime and cyanide are added to the ore pulp in the grinding circuit
