ABSTRACT:
An agitation tank adapted to contain a slurried pulp or slurry containing particles, such as carbon particles, to be separated from the slurry. The tank has a screen unit removably mounted therein, the screen unit having a hollow body provided with an opening and a screen across the opening to allow the slurry to pass into the hollow body but to prevent the particles in the tank from passing into the hollow body. The slurry in the hollow body can then pass out of the screen unit and the tank through an outlet which communicates with the interior of the hollow body and an adjacent vessel. The screen unit can be removed from the tank to permit replacement of the screen surrounding the hollow body. The screen is removably mounted on the screen unit by a clamp to permit rapid change of the screen if the screen becomes defective. The agitation tank and its screen unit can be used to form a part of a carbon-in-pulp processing system in which a plurality of such tanks and screen units are used to separate metal and other values from a slurry by adsorption of the values on carbon particles in the tanks.
