Abstract~as holdup was measured by an isolating technique in a continuously operating column (10 cm in diameter and 447 cm in height) under simulated flotation conditions. The effect on gas holdup of solid particle concentration (0-15% v/v), size (95% <53 #m, 75% >53/am) and type (hydrophilic, hydro

Electrical conductivity has been used to measure local gas holdup in the bubbling zone (holdup C&30 %) and froth zone (holdup 695 %) ofa flotation column. Models have been developed to cover the full range of dispersed phase volume fraction, based on tortuosity or effective path between electrodes.

Part I showed that the presence of solids decreased gas holdup under conditions typical of flotation in columns. Four mechanisms which might explain this effect are evaluated here: bubble coalescence, slurry density and viscosity changes, changes in radial gas holdup and flow profiles, and bubble wa
