Fundamentals of the elution of gold cyanide from activated Fundamentals of the elution of gold cyanide from activated carbon Van der Merwe ENGLISH ABSTRACT: Most research work on activated carbon systems has been concerned only with the adsorption process
The presence of spectator cations (M n+) enhances the formation of M n+{Au(CN) 2 − } n ion pairs on the carbon which in turn suppress the elution of gold cyanide The dynamics of removal of these cations determine the horizontal position of the gold peak in an elution profile

Kinetic Model for the Decomposition of Cyanide during the Elution of Gold from Activated Carbon J S J VAN DEVENTER and P F VAN DER MERWE DEPARTMENT OF CHEMICAL ENGINEERING UNIVERSITY OF STELLENBOSCH PRIVATE BAG X5018 STELLENBOSCH 7600 SOUTH AFRICA ABSTRACT Free cyanide is usually present during the elution of gold cyanide from activated
Abstract 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
27-7-1994Abstract Free cyanide is usually present during the elution of gold cyanide from activated carbon The decomposition of cyanide is important not only in the extraction of gold but also for environmental reasons Previous studies have indicated that competitive adsorption of cyanide with aurocyanide plays a minor role at the elevated

Van der Merwe (1991) and Stange (1991) showed that the elution of gold is dependent on the removal of the sodium or potassium introduced in the pre-treatment step The extent of cyanide decomposition determines the passivation of the carbon surface and the decrease in the equilibrium isotherm for gold loading (Van der Merwe 1991)

A process is disclosed for the recovery of gold and/or silver values from activated carbon wherein they are adsorbed as cyanide complexes The process uses an eluant containing sugar The process allows the eluant to pass through fresh carbon twice thereby reducing the volume of the gold-loaded eluant This in turn reduces the size of the

CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp Carbon in pulp Wikipedia Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process
This compares reasonably well with the shape of the elution profiles at this temperature found in the literature (Van der Merwe 1991) Typical industrial gold elution temperatures range from 110–130C As previously been shown in Figure 6 the amount of metal on the carbon affects the rate of adsorption of PGMs onto the carbon
