Application Note Cyanide Leach Process - pH

2020-6-18  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.
