Bubble size distribution in a flotation column Biswal The bubbles that were generated in a flotation column were measured. The bubble size distributions were obtained both for airwater and airwatercoal systems. The size distribution pattern was fitted to different equations. It was found that the bubble size distribution in both the flotation and cleaning zones follows the RosinRommler equation used to describe the particle size distribution in crushing.

Flotation columns Getting the most from fine ores OutotecFigure 2. Flotation process within a column. Typically, columns are suitable for ores with a particle size bellow 150 181;m. Larger particles tend to be too heavy to be kept in suspension. This size limit may vary depending on the ore density. Lighter ores, such as phosphate, are amenable to column flotation at larger particle sizes. Figure 3.
