Cyanide Leaching Mining SGS

Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.

Cyanide Consumers in Gold Leaching Process

Hello All, I work in a CIL plant, processing oxide ore with more and more intrusion of sulphides (fresh ore body). The plant is designed for oxide ore but we noticed that at a certain blending, the transitional ore could be processed. It impacted on the gold recovery (going from 83 84% for pure oxide to around 76 78% for Oxide transition blending) but this was within an acceptable range. The

Bacterial oxidation of refractory gold concentrates

On a plant, this effect would likely give rise to an increase in cyanide consumption as a result of the solid/liquid separation operation prior to cyanidation. It is believed that these differences in elemental sulfur content are a result of the different operating environment of the thickener in comparison to the reactor. The thickener is a quiescent non aerated operation of lower temperature
