The reversibility of adsorption of gold cyanide on

Much controversy exists about the mechanism by which gold cyanide adsorbs on activated carbon. It is not the purpose of this article to explain the exact adsorption mechanism but, rather, to investigate the factors affecting the reversibility of adsorbed gold cyanide. Whereas Au(CN) 2 − is soluble in water, AuCN and Au require the addition of cyanide to form Au(CN) 2 − .

25/04/2007· Material balance equations are developed to describe the reversible adsorption of gold cyanide on activated carbon. In this paper the carbon is divided into two interconnected regions with different kinetic characteristics. Equilibrium is assumed to exist between the liquid film surrounding a carbon particle and the gold cyanide adsorbed on the external surface of the carbon. The kinetic

The leaching and adsorption behaviour of gold ores

adsorption onto activated carbon, these effects include competing metal-cyanide complexes, preg-robbing and the mineralogy of the ore. This thesis considers these areas from an experimental and modelling viewpoint. In this research it is shown that a variety of metal-cyanide species can be used to leach gold from certain refractory ores. A mechanism is proposed which involves the dissociation

Fundamentals of the elution of gold cyanide from

As these species determine directly the need for cyanide during the elution process, the first part of this thesis was devoted to a study of the reversibility of adsorption of metal cyanides on activated carbon and the ·role that oxygen plays in the adsorption reactions. It was found that the formation of AuCN was mainly a function of the type of carbon used and that oxygen did not promote

[PDF] The mechanism of the adsorption of gold cyanide

X-ray photoelectron spectroscopy showed that the adsorption of gold cyanide on carbon in the presence or absence of electrolytes and acids proceeds by the same mechanism. Although the identity of the gold cyanide adsorbate is not known, the mechanism appears to have an initial adsorption stage that involves the adsorption of an ion pair: Mn+[Au(CN).Jn' where Mn+ is a metal ion (for example
