Abstract
The growing interest in column flotation has created a need for a fundamental scale-up procedure that is capable of meeting the necessary design and control criteria for industrial columns. Unfortunately, most of the available scale-up procedures deal with column diameter only and not overall column volume. Current work focuses on the effect of bubble size distribution and air holdup on the scale-up of column volume. A series of pressure transducers has been used to measure air holdup along the length of a bench-scale column. These measurements have been used to validate a mathematical model of the air phase. In addition to scale-up, the model appears to have the potential for use in control of air holdup and bubble size.
