Abstract

A froth flotation installation for separating solid particles from an aqueous slurry includes a tank (30) divided by baffles (139, 140, 141) into a plurality of zones. The direction of flow of aqueous slurry of unrecovered solid particles is changed by these baffles at least twice between the first froth flotation zone and the last froth flotation zone to improve solids- froth contact and to minimize the possibility of particles adopting a short circuit path through the installation. A plurality of such froth flotation zones is serviced by a single slurry pump 148. The first froth flotation zone is larger than any other so that the mean residence time of the aqueous slurry is greater in the first froth flotation zone. Agitation and aeration of the slurry is performed by vortex chambers (135-7) having the construction shown in Fig. 7. <IMAGE>
