5.2. Flotation by Mechanical Cell. This process is used to beneficiate mineral particles that are difficult to remove. These are the tiny particles of graphite. Figure 2 shows an example of flotation cell, as reported by Kuan . In mechanical flotation cells, froth is produced by agitation with a rotating impeller.

The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.

The most common examples of pneumatic cells are the column cell and the Jameson cell. As shown in Fig. 5.36, a flotation column is typically a tall vertical cylinder. It is fed with coal pulp at the top third of column. It has no mobile parts or agitators. Air bubbles are injected either through external or internal spargers at the bottom.
