Generally, the conventional flotation machine may involve four dynamic areas: agitating and mixing zone, transport zone, separation zone and froth zone. The properties of different dynamic zones in air force flotation cell are elaborated as an example combined with the flotation process of mineral particles, as shown in Fig. 2.4.

In the conventional flotation cell, the detachment of particles from the bubbles due to turbulence is the main reason for the decline in the coarse particle recovery (De et al., 2007, Fuerstenau et al., 2007).However, turbulence is imperative in the flotation cell to bring about bubble particle collision, keep particles in suspension, and disperse …

Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.

It is possible to increase the rise rate of the formed flotation aggregates, and thereby enhance the efficiency of flotation treatment via secondary saturation of the flotation cell with d b = 0.1-0.3 mm air bubbles. The air bubbles of 0.02-0.07 mm diameter float up in laminar flow regime but create light turbulence in the flotation cell.
