When the impeller rotates, the centrifugal force with the action of the impeller is produced, and drives the slurry in the impeller chamber thrown around, by which the negative pressure area is formed. The air is sucked into the impeller chamber via suction pipe and center cylinder, mixing with absorbed ore slurry, and forming a large number of tiny air bubbles. After steady flow through the cover board, these bubbles are evenly dispersed in tank, forming mineral laden bubbles. Then mineral laden bubbles will rise to the froth layer, and become froth products by the scraper.
The BF flotation cell is widely used for separating non-ferrous metal, black metal, noble metal, non-metal mineral, raw body and materials of chemical industry, like gold flotation process, which are subject to roughing and cleaning of large and middle scale floatation plants.
