Flotation behaviour in reflux flotation cell – A critical review
Flotation behaviour of minerals. To expand the application of the RFC from the coal industry to a wider range, understanding the flotation behaviour of minerals in the RFC is the key. The RFC has shown a good performance in coal flotation and it can recover both coarse and fine coal particles at a high throughput.

Advanced Techniques on Fine and Coarse Particle Flotation
Battersby et al. used pneumatic Imhoflot G-Cell flotation cells in which pico bubbles are used to obtain fine nickel and zinc. It is stated that when compared to classic flotation cells, an increase at the rate of 20% in zinc obtaining efficiency and a boost at the rate of 30% nickel obtaining efficiency are achieved.

Coarse particle flotation: A review
In the conventional flotation cell, the detachment of particles from the bubbles due to turbulence is the main reason for the decline in the coarse particle recovery (De et al., 2007, Fuerstenau et al., 2007).However, turbulence is imperative in the flotation cell to bring about bubble particle collision, keep particles in suspension, and disperse …

1 Froth Flotation – Fundamental Principles
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

Adjusting Pulp and Air Levels to Troubleshoot Flotation Cell Froth Movement
The first corrective reaction is to raise the pulp level or add air to the cells to quickly increase the overflow. As a band aid solution this is correct, but as the ultimate correction it is not. The purpose of the air is to provide the medium that the collector attaches and to provide a surface for the mineral to be floated away on.
