The gold is mixed with the sodium cyanide which leads to the following Elseners equation and reaction. This is done to make soluble gold Now the gold is soluble. This method of making soluble gold is known as leaching. In the process of leaching, a dilute form of sodium cyanide is added into the ore containing the gold.

The gold dissolution in anoxic cyanide solution in the presence of chalcopyrite was studied with a rotating disc electrode. It was found that the presence of chalcopyrite reduced and enhanced the dissolution activity of pure gold in the low and high potential regions, respectively. The dissolution of gold was diffusion-controlled at low potentials 177 mV and low cyanide concentrations ...

2014-9-8Gold is produced from its ores by cyanide leaching. The cyanide leaching process is applied by, first, grinding the ore below 75 micrometers and dissolving gold as AuCN 2-by mixing the ground ore with dilute cyanide solution to obtain slurry above pH 10 and by providing oxygen to the leaching tanks. Dissolution of gold-cyanide
