19/02/2021 · In cyanidation metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete the goldbearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore) cyanidation is accomplished by vat leaching which involves holding a slurry of ore ...

Measuring pH in Cyanide Leaching

Measuring pH in Cyanide Leaching

remove the gold cyanide, and the gold metal is produced using a process called electrowinning. Due to the rapid reactions taking place in an agitated leach process, automatic pH control is strongly recommended. pH is controlled between 11 and 12 during the leaching process. pH values below 11 favor the formation of HCN, hydrogen cyanide

Cynoprobe

Cynoprobe

Cyanide reagent costs form a significant part of a gold plant's operating budget. The Cynoprobe's free cyanide reading can be incorporated into a control scheme as part of a costsaving cyanide management strategy. The measurement frequency of the Cynoprobe facilitates tight cyanide control, less overdosing and reduction in cyanide consumption.

from the dissociation of the complex is used to leach gold from the ore. The stepwise dissociation of cyanide from coppercyanide complexes can also be used to leach gold from a variety of oxide and sulphide ores. The copper cyanide's fourth ligand readily dissociates at low cyanide concentrations for use in gold leaching.

20/10/2014 · Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.
