Getting the Gold from Carbon

The last loaded carbon needs to afterwards be removed and washed before it goes through elution or desorption of gold at high cyanide temperature and pH. Ethanol can also be utilized to desorb gold from activated carbon; nevertheless safety concerns have delayed its recognition in the gold extraction industry.

Electrowinning
The prosperous eluate consequence that comes from the elution process is passed through electrowinning cells where gold as well as further metals are precipitated onto the cathodes. The further refining of the gold is done through smelting of the cathodes material and the end result of this is gold ingots which are appropriate for transport to the refinery.
