Application Note Cyanide Leach Process
(>10.5pH) so that free cyanide (CN-) will dissolve the gold in the ore. The chemical reaction is as follows: 4Au + 8NaCN + O 2 + 2H 2 O 4Na[Au(CN) 2] + 4NaOH In this paper we will look at the various mining processes and the role that pH control plays in the gold extraction process. Gold Processing Gold ore comes in a wide variety of formations.

Leaching Low-Grade Gold Ores
Gold Ores A dilute cyanide solution is an efficient solvent of gold. However, as in any ot4er leaching process, the solvent has to come in contact with the solid gold particle. Hence, extensive crushing and meticulous two-stage, closed-circuit grinding are needed to liberate the gold particles in the ore.
