air filled flotation cells

The celltocell flotation machine is typified by a flotation mechanism suspended in an individual cell separated from the adjoining cells by an adjustable weir A feed pipe conducts the flow of pulp from the weir of the preceding cell to the mechanism

It is well known that gas dispersion is a key aspect in the performance of a flotation cell It is important to mention that the air flow rate can be calculated from the air velocity measured in a pipe placed in the air inlet of the flotation cell In some cases it could be useful to employ two different kinds of anemometers depending on the flotation cell

Froth flotation  Wikipedia
Froth flotation Wikipedia

Froth flotation depends on the selective adhesion of air bubbles to mineral surfaces in a mineralwater slurry The air bubbles will attach to more hydrophobic particles The attachment of the bubbles to the surface is determined by the interfacial energies between the solid liquid and gas phases

The air is broken into tiny bubbles by various mechanisms depending on the design of the flotation cell and the nowhydrophobic minerals attach to the bubbles rising with them to the surface of the flotation cell where they form a froth The froth flows over the top edge or lip of the flotation cell and forms the flotation concentrate
