Normally the setup is a two-stage system with 34 or 5 flotation cells in series. Principle of operation. Before froth flotation can work the ore to be treated is reduced to fine particles by crushing and grinding a process known as comminution so that the various minerals exist as physically separate grains.

Induced air flotation IAF was developed using a rotating-flow microbubble generator for water treatment. This newly-developed generator can produce fine microbubbles with diameters on the order

Model Predictive Control for Froth Flotation Plants

Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate. It is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic. In a flotation cell air bubbles then lifts the mineral.
