Magnetically separating waste particles makes it possible to reclaim a variety of raw materials from waste. Using a magnetic fluid, a waste flow can be separated into multiple segments in a single step. Researchers from Utrecht and Nijmegen have now succeeded in creating a magnetic fluid that remains stable in extremely strong magnetic fields, which makes it possible to separate materials with a high density, such as electronic components. The results have recently been published in The Journal of Physical Chemistry Letters.
