Analyze for CN- - Hydrometallurgy: Leaching in .

Likewise due to the equilibrium, the HCN may be available depending on buffering to partially replace losses in CN- (but also have some HCN losses). The CN- concentration is what is required for gold leaching and operations typically run with this in excess to oxygen, such that the leaching reaction is not cyanide ion limited. As stated above you need to evaluate and balance lime addition vs ...

Hydrogen cyanide (HCN), sometimes called prussic acid, is a chemical compound with the chemical formula HCN. It is a colorless, extremely poisonous and flammable liquid that boils slightly above room temperature, at 25.6 °C (78.1 °F). HCN is produced on an industrial scale and is a highly valuable precursor to many chemical compounds ranging from polymers to pharmaceuticals.

Application Note Cyanide Leach Process - pH

Cyanide Leach Process - pH Mining: Gold Processing While there are many different processes to remove gold from its encapsulating ore, cyanide leaching (cyanidation) is perhaps the most common and well known. A cyanide solution (NaCN or KCN) is elevated to a high pH level (>10.5pH) so that free cyanide (CN-) will dissolve the gold in the ore. The chemical reaction is as follows: 4Au + 8NaCN ...
