Zeta potential of air bubbles conditioned with typical froth flotation
The effect of chemical flotation reagents on the zeta potential (ζ) of particles is well known, but their effect on bubbles is practically unknown. This study characterizes the ζ of air bubbles conditioned with typical froth flotation reagents and presents a novel experimental setup and method for estimating the electrophoretic velocity.
