Formatted Abstract/Summary
Froth stability is widely recognized as a key driver of flotation selectivity. It is well known that froth
stability is affected by the type and quantity of surface active reagents present (frothers), and the
concentration and hydrophobicity of solid particles present.
While some studies have been performed on the effect of frothers on froth stability in three-phase
systems and the hydrophobicity of particles present, very little work has been performed on the effect
of solids loading on froth stability. This may be due to insufficiently robust measurement techniques.
This paper investigates the use of a new machine vision measurement to measure solids loading, and
the relationship between this measurement, bubble size, and bubble burst rate on the froth surface.
