Apparatus for treatment of a pulp of a liquid and particulate material, and a process for such treatment, in which a chamber defined by a housing is divided by a partition (20) to provide an agitation zone (24) and, adjacent the upper region of the latter, a recovery zone (26); there being agitation means for circulating the pulp vertically in the agitation zone (24) to provide a flow of the pulp down past at least one slot (22) providing communication between the zones (24, 26) at the lower edge of the partition (20). The arrangement is such that with operation of the agitation means and feed to the agitation zone (24), the pulp is caused to circulate vertically in the agitation zone (24) to provide flow of pulp downwardly past the slot(s) (22) so that a flow of the liquid occurs between the zones (24, 26) with particulate material being transported therewith to the recovery zone (26) and settling in the recovery zone (26) for subsequent return to the agitation zone (24). The apparatus and process enable separation of the liquid and particulate material with treatment of one by the other. |
