Measurement of flotation reco­very by means of 4D particle tracking velocimetry

The efficiency of the froth flotation process depends on the encoun­ter of particle and bubbles based on the hydrodynamics within the cell and the surface chemistry of the pulp for the film rupture during the attachment process.

Se­paration of plastic particles by froth flotation

The quantity of plastic waste is rising e­very year, which calls for the development of appropriate technology for proper ­manage­ment. Froth flotation is one of the promising methods for se­parating plastics.

Particle motion in the froth

The motion of hydrophobic valuable mineral particles in the froth is decisive for the reco­­very rate in flotation while the motion of hydrophilic particles strongly influences the grade of the concentrate. Particle motion is investigated in our group by new techniques.

Removal of inclusions in liquid metals by flotation

The removal of non-metallic inclusions from liquid metal alloys by means of gas bubbles is important to ensure clean and high-quality structural materials. The project aims on a bet­ter understanding of interactions, e.g. collision and attachment, between bubbles and inclusions.

Process intensification in flotation using ultrasound

Ultrasound in a promising technique to increase the reco­very of mineral particles in flotation. Our focus is on studying the mechanisms underlying this increase.

Carrier flotation

To remove ­very small particles from suspension an upscaling of their sizes, e.g. by stimulating their attachment to larger carrier particles (e.g. calcite for collecting TiO2 fines) is desirable. Currently, works with magnetic carrier particles are ongoing.
