Introduction to Cyanide Gold Mining

The method of recovery of gold from the process slurry is by carbon adsorption. • Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material. • Activated carbon is used to adsorb the gold out of solution. Because the cyanide ion forms very strong complexes with gold, it is the gold cyanide complex that is loaded onto the carbon rather than ...

Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.

Process of Cyanide Gold Extraction

Pachuca aeration gave better gold extraction and lower cyanide consumption than bottle agitation. With the former more copper was found in solution, and less thiocyanate was formed; with bottle agitation the reverse was the case, in addition to which copper cyanogen complexes were found in the filter cake. From this it was concluded that gold dissolution depends not only on the presence of ...
