Method of desorbing gold from activated carbon THE

The gold-cyanide complex may also be removed from the cyanide solution by adsorption on activated carbon which is then separated from the leach solution, stripped of its gold content, and subsequently regenerated by a heat treatment prior to reuse in the adsorption step.

Carbon Adsorption In Recovery Of Gold Mine

2013-1-12  The gold adsorbs onto the surface of the carbon. The loaded carbon is periodically removed from the columns, and sent to the stripping circuit. The carbon is then generally subjected to a heated solution (200 deg to 250 deg F) of (1%) sodium

Activated Carbon for Gold Recovery Puragen Activated

Activated carbon is then used to separate and store the gold, which is removed as the final step of the process. There are three basic operating systems in use for modern gold recovery: Carbon in Pulp: Carbon in pulp, or CIP, processing occurs when the leaching takes place in an agitation tank before the activated carbon is introduced.

The mechanism of elution of gold cyanide from activated

Numerous articles have appeared on the mechanism of the adsorption of gold cyanide onto activated carbon. In contrast, little information is available on the mechanism of elution of the adsorbed gold. It is the objective of this article to formulate such a mechanism on the basis of batch and column elution tests without analyzing adsorbed species on the carbon directly. The presence of

The macropores allow for the rapid movement of adsorbates (species that will be adsorbed by the carbon, e.g. gold) into the activated carbon granules. Mesopores (100 Å to 500 Å) these are the pores that branch off the macropores that serve to allow the adsorbates to leave the macropores

Process of stripping gold and silver from carbon Drew

1990-9-26  Abstract: Gold and silver are stripped from activated carbon on which they are adsorbed as cyanide complexes by subjecting the activated carbon to a stripping solution comprising as the strippant an effective amount of a compound containing the carboxylate functionality. The compound is preferably selected from benzoic and substituted benzoic

Gold complexes and activated carbon SpringerLink

Exciting new developments are taking place in the extractive metallurgy of gold, which are based upon the adsorption of the metal or its complexes on carbon and subsequent elution. Despite the efforts of investigators over a period of almost 70 years, however, the mechanisms of the adsorption and elution processes have not yet been established unequivocally. The literature relating to them is
