vertical carbon in column design for gold mining processing
The gold absorbs onto the surface of the carbon. The loaded carbon is periodically removed from the columns and sent for stripping. With at least four Vertical Carbon-in-Carbon (VCIC) Plants commissioned in the past two years in Nevada alone, a vertical plant design is something you might want to consider.
