Carbon-In-Column Jacobi Group
2022-5-17 Carbon-In-Column. With carbon-in-column operation, the gold cyanide solution flows through a series of fluidised bed columns in an up-flow configuration. Fluidised bed carbon columns can process solutions that contain as much as 2 to 3 wt% solids, thus making them well suited for heap leach applications which are often high in solids content.

The mechanism of elution of gold cyanide from activated
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 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.
