Abstract
An improved froth flotation installation for separating solid particles from an aqueous slurry by delivering a stream of the aqueous slurry directly into a vortex chamber along with a supply of bubble-forming gas. The kinetic energy of the slurry creates necessary froth bubbles, and provides mechanical agitation of the contents of a froth flotation separation zone upon discharge from the bottom of the vortex chamber. In multi-zone froth flotation installations, the direction of flow of the aqueous slurry of unrecovered solid particles is deliberately changed at least twice between a first froth flotation zone and a last froth flotation zone to improve solids-froth contact and to minimize the possibility of particles adopting a short circuit path through the installation. Multiple froth flotation zones are serviced by a single slurry pump in a preferred embodiment.
