Sep 15, 2005· flotation circuit. Flotation cells have three main control parameters (1) reagent dosing rate (2) froth depth and (3) air addition rate. Many other parameters may vary such as feed rate, particle size distribution and head grade, however these are the output of upstream processes and are not controlled in the flotation circuit itself.
Mining Flotation. One of the most widely used methods of recovering useful minerals in the mining industry is the use of froth flotation tanks. This technology provides superior control over the floatation cell for the extraction of minerals, maximising efficiency and profitability.
In Mineral Processing Design and Operations (Second Edition), 2016. 18.5.1 Batch Flotation. The concentrate obtained from a batch flotation cell changes in character with time as the particles floating change in size, grade and quantity. In the same way, the concentrate from the last few cells in a continuous bank is different from that removed from the earlier cells.

Flotation columns comprise a tall tank, in which the separation between froth and pulp occurs, an aeration system, a pulp level control system, a wash water system, a discharge barometric leg and a set of control instruments, besides pipe connections for feed, concentrate and tailings. Figure 1 illustrates a typical column. Figure 1.
To work efficiently, flotation cells depend on continuous froth formation. If the froth layer is too thin, it cannot transport the sufficient amount of dispersed or suspended particles to the surface. On the other hand, froth that is too thick indicates that the reaction time of the chemicals is too long.
Separating minerals in a froth flotation cell has a particularly corrosive effect on a slowly rotating rake and its components. Mixtures of slurry, surfactant, water, air and froth can quickly lead to failed seals and bearings. Which, of course, means costly unplanned downtime and lost productivity.
