Froth flotation - Wikipedia

Mar 04, 2005  Normally the setup is a two-stage system with 3,4 or 5 flotation cells in series. Principle of operation. Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution)

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.

US4247391A - Froth flotation cell and method of operation ...

Coarse particles of up to 3 mm are floated in a cylindrical froth flotation cell in which the agitation impeller has a cover preventing fluid from being drawn in above. Air is supplied from a ring around the periphery of the cell and situated above the cover. Baffles project radially inwardly up to a short distance from the top. Froth is allowed to overflow around the periphery of the cell.

Flotation Circuit - an overview ScienceDirect Topics

Froth flotation depends on differences in surface properties between coal and shale. Air bubbles are generated within an aqueous suspension of fine raw coal with a solids concentration of less than 10%. The hydrophobic coal particles attach to the air bubbles and are buoyed to the top of the froth flotation cell where they are removed as froth.
