This enabled the calculation of a shifting gold cyanide equilibrium isotherm as a function of time and position in the column. The elution of the gold cyanide was found to be diffusion controlled only under conditions of weak desorption. Under these conditions, the desorption of the gold cyanide was simulated with a model accounting for mass ...

This article serves to discuss the fundamental aspects of gold recovery utilizing the Carbon-in-Pulp or Carbon-in-Leach processes. The purpose is to describe in simple terms what activated carbon is all about and how it adsorbs gold. The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as
