Enhancing Fines Recovery by Hybrid Flotation Column and …
The froth flotation technique can be considered one of the most efficient methods for the separation of minerals. Prior to utilizing any physicochemical separation method, the size of the mined ore must be decreased to facilitate the release of the valuable materials. This practice, along with the increased exploitation of ores that carry fine …

It is known that flotation of minerals/particles by a conventional mechanical flotation cell is typically applicable for a particle size range from 10 to 100 μm [ 32 ]. Floatable particle size range can also be varied with mineral type/density, and the maximum size can be extended to 500 μm [ 14, 33, 34 ].
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.

The future of flotation
Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns. The research to date has identified two main reasons for the upper limit on floatable particle sizes.

A froth flotation cell consists typically of a collection zone (or pulp zone) located below the feed particle point, and a cleaning zone, (or froth zone), above the particle feed point [26] (Figure 2). The collection zone is fed back-stream by the pulp pushed by the bubble swarm created by a gas sparger at the bottom of the flotation cell.
