Extraction of Gold
The solution of gold in the cyanide solution is accompanied by the intermediate formation of hydrogen peroxide, and the process is accelerated by addition of this substance: 2 Au +4 KCN +2 H2O + O2 = 2 KAu (CN) 2 +2 KOH + H2O2; 2 Au +4 KCN + H2O2 = 2 KAu (CN) 2 +2 KOH.

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.

Extracting Gold HowStuffWorks
Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
