Cyanide is utilised in the extraction of gold from its ore. It is used in electroplating industries, metal plating industries and polymer synthesis; these activities have caused contamination to the environment by altering the biogeochemical cycle (Parmar et al. 2012).The release of cyanide into the environment inflicts severe hazard to the maintenance of the ecosystem …

Gold CIL & CIP Gold Leaching Process Explained CCD

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to ...

Improvements to the cyanidation process for precious metal ...

The gold and silver content is significant in WPCBs, therefore the extraction of these metals is a highly profitable process. In addition, WPCBs have other precious metals such as Pt, Pd, and Rh, which can also be recovered by dissolution. However, the high copper content is detrimental to the cyanidation process as well as in further refining processes.

Cyanide Process. Cyanide process is also called as Macarthur-forest Process. It is the process of extracting gold or silver from the ores by dissolving in a dilute solution of potassium cyanide or sodium cyanide. This process was introduced in the year 1887 by the Scottish chemists naming Robert W. Forrest, John S. MacArthur, and William Forrest.
