Dense Medium Separation - An Effective and Robust Pre ...

Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.

2. The stability of the medium. A typical dense medium bath is relatively deep, and this makes it difficult for the suspension particles to remain in suspension. If a medium is not stable, we find water at the top of the bath and a dense sludge at the bottom of the bath, and of course, in this stratified liquid, no separation takes place.
