| Elsner's equation | Mining | In dissolution of gold by dilute aerated cyanide solution this reads: 4Au + 8NaCN + O2 + 2H2 O = 4NaAU (CN)2+4 NaOH. Analogous equation is given for silver. Other mechanisms have been suggested by Janin and Bodlaender, the latter requiring two stages of reaction with the intermediate formation of hydrogen peroxide.
