Elution behaviour of metals from carbon

2009-10-15  ELUTION BEHAVIOUR OF METALS FROM CARBON 475 Introduction Gold can be extracted industrially from ores by a variety of processes, and one of the most successful methods is the carbon-in-pulp (CIP) process. In CIP processing, ore is mined, ground, and leached with alkaline cyanidic solution to solubilize the gold as a gold cyanide complex.

Factors affecting the elution of gold cyanide from ...

1994-1-1  Adams and Nicol [4] listed the most significant influences on elution, in order of decreasing importance, as follows : temperature, cyanide and hydroxide concentrations, and the ionic strength of the eluant. Likewise, Davidson [5] considered the temperature and reagent cyanide addition to be the most important factors affecting gold elution.

Strategies for the optimisation of gold processing plants

For efficient stripping of gold, from activated carbon, reversing the above is logical. Thus successful elution should be favoured by high temperature, high free cyanide, high pH, low ionic strength and the absence of calcium. This is an excellent starting point to commence elution optimisation.

A new elution process has been developed for the recovery of gold thiosulfate from ion exchange resins. This is a synergistic system which utilises a base eluent, such as nitrate or trithionate, along with an additive that improves the elution of gold. The use of the additive enables lower eluent concentrations to be adopted, as well as weaker eluents such as chloride.
