In flotation, the froth characteristics strongly influence the separation process as they are
linked to water recovery, bubble size, entrainment of gangue particles, flotation rate …

The liquid fraction of foam is an important quantity in engineering process control and
essential to interpret foam rheology. Established measurement tools for the liquid fraction of …

This work provides evidence that anisotropic drainage in sheared foam is at the origin of
convective instability in very long foam channels. Convective instability occurs in foam under …

Liquid drainage through foam is dominated by gravity, capillary, and viscous forces. The
liquid is conducted by an isotropic network of Plateau borders; however, imposed stress …

We investigate argon bubble flow in liquid gallium within a container large enough to avoid
wall effects. Flow with and without applied horizontal magnetic field is studied. We …

In this work, we introduce a novel approach to measure the flow velocity of liquid foam by
tracking custom-tailored 3D-printed tracers in X-ray radiography. In contrast to optical …

The significance of clusters in the flotation of coarse particles is well-known. This paper
presents a novel technique for micro-computerized tomography (micro-CT) imaging of …

Unwanted mineral solids in bitumen froth can lead to increased solvent usage and higher
hydrocarbon loss in downstream processing, negatively impacting the cost-effectiveness …

In mineral processing, froth flotation is based on recovering valuable mineral particles by
means of the overflowing froth. Industrial-scale froth flotation cells are typically equipped …

Flotation is an important process in liquid–solid and solid–solid separation, whereby desired
solids in suspensions are recovered by their attachment to gas bubbles. Monitoring the …
