balanced chemical equation for mining gold

balanced chemical equation for mining gold. How can the chemical equation for gold be balanced? Quora. The most common ionic states for gold are +1 and +3. So, for example, gold chloride would be AuCl, where the Au+ bonds with the Cl in ionic bonds. This would easily balance as: 2Au + Cl2 > 2AuCl In the oxidation state of +3, as in Au2Cl6, with bo...

Gold cyanidation - Wikipedia

The chemical reaction for the dissolution of gold, the "Elsner Equation", follows: 4 Au (s) + 8 NaCN (aq) + O 2 (g) + 2H 2 O (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.

Cyanide Leaching Chemistry Gold Cyanidation

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
