TECHNICAL NOTES 9 FLOTATION - mineraltech
· froth layer. Particles that are retained in the froth are recovered at the lip of the froth at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the and the recovery is sometimes assisted by mechanical paddles.

CONTROLLING FROTH FLOTATION - TECHNOLOGICAL …
A method of controlling a froth flotation cell in a froth flotation circuit for separating substances is disclosed. The method includes controlling flotation gas flow rate to the cell based on changes in cell conditions to maintain the operation of the cell at a peak froth stability of the cell or closer to the peak froth stability of the cell than if the flotation gas flow rate was not changed.

Effects of Operating Parameters on the Froth and ...
The effects of flotation operation parameters, including froth depth, air flowrate, and frother dosage, on the froth and collection zone recovery and the flowrate of particles into the froth phase were investigated in a 10 m3 industrial cell. The results showed that froth recovery increases upon increasing air flowrate and frother dosage, as well as reducing froth depth.

Froth Flotation Process - Mineral Processing & Metallurgy
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.
