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.
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.
