The Pumpcell is in essence a complete CIP plant incorporating a Pumpcell mechanism and launder system enabling the carousel mode of operation to be employed. The carousel mode of operation involves keeping the carbon in a discreet batch within each contactor and rotating the pulp feed and discharge positions.

A process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.

[PDF] Dynamic simulation of the carbon-in-pulp and carbon-in-leach
Carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur

Pulp and Paper Industry
Pulp and paper production has increased globally and will continue to increase in the near future. Most of the pulp and paper mills are located near the major waterways and have an access to a large, uninterrupted supply of water. After using the water for pulp and paper production, these mills discharge the used water into the waterways as waste.
