Flotation Process
The use of power ultrasound in mining. L. Gaete-Garretón, in Power Ultrasonics, 2015 35.5.1 The flotation process. One of the most used processes to concentrate mineral from a mine is flotation. To perform a flotation process the mineral is finely ground (particle sizes between 50 and 150 μm), then the ground mineral is mixed with water in a …

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.

SELECTION OF MECHANICAL FLOTATION EQUIPMENT
Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the

Flotation Cells Design & Operating Characteristics
In its essentials, a flotation cell must provide for two main functions. First, it must supply air adequate in quantity and quality for satisfactory process kinetics. Air quantity can be defined on the basis of the narrow range provided in major U. S. commercial cells, for escape velocity, which averages near 1.2 m/min (4 ft /min).
