froth flotation operations

Froth flotation cell

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.

Column Flotation

The froth of a flotation column is usually . water washed, with approximately as much wash water as there is water reporting to the froth. The water is most commonly added via pans, perforated with 4-8 mm diameter holes, located 20-30 cm above the froth, thus generating a "rain" of water onto the surface of …

The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.

Flotation Froth

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
