Zinc precipitation on gold recovery
This section deals with setting the gold free from the gold-cyanide solution. Main reactions are the deposition of gold on the surfaces of zinc particles. There are two half cell reactions representing this, the first one being the reduction of gold by zinc. Gold cyanide loses an electron to form Au and ion. The zinc introduced then reacts with
