the selective solubility of gold in a weak cyanide solution. 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.

 · Gold is a kind of inactive metal, which can cause complexation reaction with cyanogen (CN) under the action of oxygen in the cyanide leaching process, and then results in Au (CN) 2. Therefore, cyanide agent dosage is one of the key factors determining the gold dissolution. In general, the pulp should contain a certain amount of unbonded ...
