A forced air flotation machine typically has stable, consistent froth flow over the lip at the top of the machine. This is because the rotor is located at the bottom of the and the tank distance of the rotor to the froth zone minimizes turbulence in the upper region, which is conducive toa stable froth zone. As previously
There are certain variable factors which affect the Fundamental efficiency of a Flotation Machine. These factors, having different degrees of importance, are as follows: Type of Froth Flotation Machine Mesh analysis of the pulp Density of the pulp Reagents and pH Pulp temperature Conditioning Circulating load Contact period Aeration Of these …

Flotation utilizes the fact that the metalliferous ore particles, and the gangue minerals have different interactions with water. Fundamentally floatation relies on the fact that hydrophobic ore particles and hydrophilic gangue particles can be separated. Hydrophobic means water fearing and hydrophobic substances fundamentally repel water. Hydrophilic means …

Dahlke and Gomez (2005) showed that in a flotation machine operating in a typical range of the superficial gas velocity J g, the gas holdup e was directly proportional to J g. For a given cell, J g is simply the gas volumetric flowrate Q g, m 3 /s, divided by the area of cross-section of the cell, so holdup is proportional to the gas rate Q g.
