Gold cyanidation - Wikipedia

The chemical reaction for the dissolution of gold, the "Elsner Equation", follows: 4 Au(s) + 8 NaCN(aq) + O2(g) + 2H2O(l)→ 4 Na[Au(CN)2](aq) + 4 NaOH(aq) In this redox process, oxygen removes, via a two-step reaction, one electron from each gold atom to form the complex Au(CN) 2 ion.
