An Induced Gas Flotation (IGF) machine is a water treatment device that utilizes the flotation characteristics of air bubbles (Yiantos, 2007 ). The working principle of an IGF is that air bubbles are directly injected into the vessel and forced through a flow passage. Then, the discharged air spreads through the entire IGF vessel via a rotor.

How Froth Flotation Works. To start with I will give you a simplified description of how selective froth flotation works, lets start over again with a description of the equipment and why it works. When the grinding circuit is finished with the ore it will be ground very fine and the density of the slurry will be between 30% to 45% solids.

Bubble size dictates the carrying capacity of a flotation machine. Finer bubbles increase the carrying capacity (often measured as the mass flow rate (tonne/h) of concentrate per m2 of surface area of the flotation machine) as there is more bubble surface area per volume of air added for particles to attach. Essentially, this means

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 attached air bubbles are then carried to the surface and removed, while ...
