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.

4 Common Problems and Solutions Met in the Flotation Cell

As the core part of flotation cell, agitation mechanism is directly related to the function of flotation cell. After some parts of the flotation machine are replaced, sometimes the agitation mechanism is not flexible, even cannot run, or there are some problems of motor bearing (too high temperature, abnormal vibration, noise).

Laboratory Flotation Characterisation of a Uranium

4) Batch Flotation A series of batch flotation tests was performed separately on each ore type under identical conditions in a 2L Agitair cell. Test conditions such as agitation (600 rpm), aeration (6 ml/min) and collector dosage (50 ppm) were predetermined. The flotation conditions used throughout the test are summarized in Table 2.

HYBRID FLOTATION RECOVERY OF MINERAL BEARING ORES

Inside the flotation cell, the finer mineral particles and the coarser mineral particles are separated and moved to different zones. The coarser mineral particles, partly due to their momentum, tend to stay near the cell wall in the zone herein referred to as an interior periphery volume. As an impeller is used to stir the slurry inside the
