In this study, Particle VisionMeasurement (PVM) and Focused Beam
ReflectanceMeasurement (FBRM) instrumentswere installed in the flotation
cell to measure the enlarged size of clay minerals by PEO under
dynamic flotation conditions. In the previous studies, the enlarged size
was measured ex-situ and then correlated with the decrease in gangue
mineral flotation recovery. This does not reflect the true size that necessitates
the reduction of fine gangue entrainment in flotation. This study
will provide a guideline to apply in-situ measurements of PVM and
FBRMand polymeric flocculation in flotation to reduce fine gangue mineral
entrainment in industry practice.
