Dense medium separation (or heavy medium separation (HMS), or the sink-and-float process) is applied to the pre-concentration of minerals, i.e. the rejection of gangue prior to grinding for final liberation. It is also used in coal preparation to produce a commercially graded end-product, clean coal ...

The Ad Rem heavy media separation system has been developed in close cooperation with the Galloo Recycling group and the University of Leuven. Together we have developed and validated a numerical model to simulate the current material flows in our separation drum. This was done by using complex computational fluid dynamics.
