Bubble Size Analysis and Boundary Conditions for Automatic
To evaluate the gas dispersion in large flotation cells, the bubble surface area flux (Sb) must be estimated according (1) (Finch and Dobby, 1990) where Jg is the superficial gas rate and D32 is Sauter mean bubble diameter. All these variables can now be measured in plant operations.
The uncollected particles are removed through an underflow line. As with a flotation column, the froth may be water washed meaning the contact cell can also be used as a cleaner cell. The contact cell is mainly used in rougher flotation circuits. It is compact, highly efficient, simple to operate, and has low energy and maintenance costs.
A Benchmarking Tool for Assessing Flotation Cell Performance
Re (Equation 8), is a measure of inertial to viscous forces and will increase in proportion to the rotor diameter if tip speed remains constant. N Re for flotation cell impeller design is always well into the turbulent region (>>103) thus N P remains constant for a particular rotor design, and so N Re does not impact directly as a scale up
