Flotation

Dissolved air flotation Induced gas flotation Froth flotation, typical in the mineral processing industry DISSOLVED AIR FLOTATION.

The removal is achieved by dissolving air in the

[PDF] 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 attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay in the liquid phase.

The Effects of Frothers and Particles on the

froth. Since flotation is a surface area (of gas) driven process, the size and behavior of bubbles in both pulp and froth phases are of paramount significance. In addition, according to the penetration theory proposed by Leja and Schulman [1], frother molecules at the gas/liquid interface interact with collector molecules adsorbed on mineral particles. It is evident, …

Froth flotation process and its application

Froth flotation is one of the steps which is generally performed before roasting and it deals with the surface chemistry of liquids and of the minerals to be separated. This process requires a particular setup to be performed which contains different components. Surfactants play the most important role here. Different types of surfactants are used in different ways and each of them …
