Flow Patterns

The impeller in a mechanical flotation cell, during rotation, generates a vortex at the bottom of its blades drawing slurry from its lower section and discharging out from its upper section of the blades. Air is introduced through the impeller shaft or in the spacing between the shaft and a standpipe depending on whether the cell is forced air type or self-induced type, as described above. The dispersed air bubbles come in contact with the slurry close to the impeller discharge point. The aerated slurry flow then leaves the impeller mechanism for the surrounding tank volume. The impeller, therefore, acts as a pump drawing in slurry from below and expelling the aerated slurry to the cell volume. A typical flow pattern of a mechanical cell is shown in Figure 4.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
