Cyanide Leaching Chemistry & Gold Cyanidation
Feb 06, 2015 The reactions that take place during the dissolution of gold in cyanide solutions under normal conditions have been fairly definitely established. Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu(CN)2 + 4 NaOH . Cyanide Leaching Chemistry
About this site
The gold is mixed with the sodium cyanide which leads to the following Elsener’s 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.

Nov 01, 2005 1.. IntroductionGold cyanidation has been reported to involve the chemical reactions shown in Eq. (Bodländer, 1896) and Eq.(Elsner, 1846), where Eq.(3) can be treated as the sum of the two partial reactions shown in Eqs., .Hydrogen peroxide produced at the interface by reduction of oxygen can react with gold (, or with cyanide ion (Eq.
