carbon columns for gold

Carbon-In-Column - Jacobi Group

2021-11-8  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.
