In ore flotation, a higher bubble surface area flux usually means a higher probability to achieve the maximum recoveries [17]. In ion flotation, however, higher Sb values mean unfavorable hydrodynamic conditions to achieve good recoveries in a flotation cell with spargers.

Froth flotation

The Jameson cell uses neither impellers nor spargers, instead combining the slurry with air in a downcomer where high shear gives excellent bubble particle contacting. In dissolved air flotation (DAF), which is used in wastewater treatment, air is dissolved into the flotation solution under high pressure.

SPARGERS AND SPARGING TECHNOLOGY

Spargers are an industry tool designed to deliver gas into a column flotation cell or leach tank to ensure that bubbles are dispersed evenly throughout the flotation cell or leach tank. Typically, a column flotation cell can contain up to 20 spargers in order to help the reaction in the cell while up to 16 spargers can be used for a leach tank.

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.

 · 3.2.. Three-hole sparger (0.1 mm) and flotation cell testsSince the frothers do not affect the size of bubbles generated using a single-hole sparger, the only possible mechanism to change the bubble size when a multi-hole sparger (or a flotation cell) is utilized would be by coalescence and/or breakage of the bubbles.

Flotation Column

Columns cells also differ in the way gas bubbles are generated. Air is either injected directly into the cell with use of internal spargers, or is carried into the cell through a high velocity recirculated stream of tailings. The air input can then be controlled depending on concentrate grade or varying throughputs. 3. Features of Flotation Column
