ABSTRACT:
A superb centrifugal flotation cell with a rotating feed, is provided for use in an effective separation process to rapidly recover greater quantities of valuable fine particles. In the process, a slurry of fine particles is injected with air bubbles and moved downwardly through a stationary pipe and a rotating feed line comprising a centrifugal rotating downfeeder. The slurry is centrifugally discharged from the rotating downfeeder into the flotation chamber where the slurry is separated into a waste stream of non-floating gangue material and a particulate-enriched froth comprising air bubbles carrying a substantial amount of the valuable fine particles for further processing.
