Numerical analysis on performance of induced gas flotation …
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.

Froth Flotation Machines
The successful operation of a flotation machine hinges around the air and pulp mixture. Maximum results are obtainable when each particle of mineral is brought into direct contact with a bubble of air. This can only be secured by maintaining a thorough mixture of air and pulp during the entire flotation period.

New directions in flotation machine design
The flotation feed is introduced into the fluidized bed, and air bubbles are dispersed in the fluidizing water. Coarse particles attach to the bubbles rising through the bed and are lifted into the froth layer that is maintained on top of the cell in the usual way. Particles of galena up to 1 mm in diameter have been recovered in such a bed ...

A Review of Flotation Physical Froth Flow Modifiers
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the …
