Flotation Feed an overview ScienceDirect Topics

For best operation a cell should operate well below the flooding gas velocity. Flooding results in very large bubbles, which are of little value for flotation. For example, it is found that a reduction in air flow to an induced air flotation cell by closing off part of the air intake can substantially improve the recovery.

Figure 1 illustrates the features of the StackCell technology. During operation, feed slurry is introduced to the cell through a side (or bottom) feed port. At this point, low pressure air is added to the feed slurry. The aerated feed slurry then travels into the aeration chamber where significant shear is

US4247391A Froth flotation cell and method of operation

Coarse particles of up to 3 mm are floated in a cylindrical froth flotation cell in which the agitation impeller has a cover preventing fluid from being drawn in above. Air is supplied from a ring around the periphery of the cell and situated above the cover. Baffles project radially inwardly up to a short distance from the top. Froth is allowed to overflow around the periphery of the cell.

Hydrodynamic Characterization of Industrial Flotation

operation considers the arrangement of cells in banks. Thus, banks of 5-10 cells in series are commonly used in plant practice. The largest flotation cells presently used in industrial flotation operation are 130, 160, 250 and 300 m3. Figure 1 show the main characteristics of a self-aerated mechanical flotation cell, where the feed pulp circulates

Operating Principles Operating Principles Jameson Cell

The Jameson Cell consistently produces fine bubbles and intense mixing between air and slurry. This means fast, efficient flotation. While the principle of using air bubbles to recover particles is the basis of the technology, it is the way air bubbles are generated and how the bubbles and particles interact that make Jameson Cells unique.
