Flotation columns getting the most from fine ores

Flotation process within a column. Typically, columns are suitable for ores with a particle size bellow 150 µm. 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.

1 Froth Flotation – Fundamental Principles

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
