Gold is very unreactive and is found as a native metal in the free state. So, it does not need to be chemically separated. Thus, gold is leached to get pure metal. During leaching process, gold Au is first oxidized by oxygen of the air to Au cation which then combines with CN-ions to form the soluble complex, sodium dicyanoaurateI..Feb 23, 2009 Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
