In froth flotation, entrainment is the dominant recovery mechanism for fine gangue mineral particles, and it is influenced by a number of factors in both the pulp and froth phase, including particle properties (e.g. particle size and density)
vi froth by both true flotation and entrainment. These fine particles would result in a higher interfilm viscosity resulting in reduced drainage. A useful linear relationship between froth stability and the reciprocal of feed particle size was obtained. The reciprocal of feed

The Basics of Froth Flotation. June 2015 by Chris Ralph. I thought it might be worthwhile to take a look at the basics of this important mineral separation technique and how a miner can use it to recover the values out of an ore. Online access required. Please LOGIN HERE.
In the literature study, it was found that a flotation cell has many sub processes which are connected from the mixing zone in the bottom to the top of the froth. These sub processes have an effect on each other and it makes the flotation a complex process.

1 1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with
Froth flotation can be used for the separation of hydrophobic materials from hydrophilic ones and can be used at laboratory scale, but also at industrial scale. Membrane filtration may be used for the fractionation at molecular level based on differences in the molecular weight of the sample components.
Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
Froth stability was measured using a column similar to that used by Zanin et al. (2009) and McFadzean, Marozva, and Wiese (2015) (Figure 2). Froth recovery Froth recovery was calculated using froth height changes (Equation ). Recall that at the maximum
